A pressure reducing valve is generally used to reduce the pressure of a media from a high to a lower safe working pressure. However it can also provide a form of temperature control when utilised on a steam system. For example this could be used in process applications where a product is sensitive to high temperatures, causing product spoilage during the heat transfer process. In a saturated steam system the steam pressure is directly related to the steam temperature.

Hammer arresters absorb sudden pressure changes to keep the pipes from banging, providing continuous and maintenance-free protection against water hammer.

The chart on the submittal data sheet is the flow chart for measuring the flow. The actual pressure drop, with the balancing valve wide open, can be calculated by using the Cv or the slide rule.

There are many reasons why your rooms are not reaching temperature. What is the outdoor temperature at the time the rooms would not heat? Were the zone valves open? You can check by pulling down on the manual lever. If there is no resistance, the valve is open. You should read 24V across terminals #1 and #2 if the zone valve is activated.

To help divert flow from a given zone to a bypass loop when the flow is not adequate to satisfy the load at that branch of the main loop.

There are several reasons: 1.The 570 series can only hold back 50ft of head and if you have a pump upstream of the valve producing more than 50 ft, the valve will be pushed open. 2.If the manual lever has been pulled down, the valve will be manually opened. 3.Depending on the environment the zone valve is in could cause the piston of the operator to stick and not allow the valve to close.

Push the piston back into place using a blunt object, and then place the power head back on the valve body & apply power to reheat the head. Power head will return back to its normal operating mode once it is reheated.

The Flo-Chek serves two purposes: It prevents flow from going in reverse direction from the arrow on the valve, and it prevents thermosiphoning when the pump is not running. Thermosiphoning is a condition in which water in a heating system rises when it is hot and sinks when it is cool. The home can be heated if the pump is not working by manually lifting the disk of the Flo-Chek. This can be done by screwing the stem counter clockwise, which will lift the stem and disk.

Something has adhered to the Flo-Chek seat or disk. The Flo-Chek is a weighted disk check valve that normally prevents thermosiphoning. That is, it prevents the lighter, hot water from rising to the radiation and the heavier, cool water from sinking, causing a flow in the system without a pump. If the system worked fine before and then started to act up, the disk is stuck or something is on the seats.

This really depends upon the environment and the quality of the media that the valve operates with. The installation of line size strainers upstream of any Pressure reducing valve is highly recommended to reduce the amount of dirt and other impurities from entering the valve internals. A correctly selected and sized Pressure Reducing Valve should perform for many years. In particular with steam installations, it should be installed in accordance with good steam fitting practice and it is highly recommended that regular internal inspection of the valve is carried out at least once a year and cleaned or repaired as required. This will give the valve the best opportunity to continually operate satisfactorily for many years.

The bypass knob should be turned clockwise all the way for normal operation. For bypass mode, turn the knob counterclockwise until you have reached the position desired.

Pipe the system as primary /secondary with a pump circulating the primary loop and using 2 tees close together with the branch of the one Tee supplying the hot connection of the tempering valve and the return from the radiant loop supplying the cold connection of the valve and the branch of the other Tee. A pump, sized for the radiant loop or loops should be pumping the mixed port of the valve and supplying the radiant loops.

Taco no longer makes this product and we don’t have any replacement elements. The PANELTROL was designed to reduce the water temperature being supplied to a radiant panel loop. The reduction in water temperature allowed the radiant loop to operate at a lower temperature than the boiler, which might be needed for other higher temperature requirements. The return water from the radiant loop is used to temper the hot water. Taco does make a new tempering valve, the 5000 Series Valve, that could take its place. The PANELTROL had 1¼” connections but our 5004-C1 should work.

As in any troubleshoot procedure it is important to isolate the problem. The error messages greatly simplify troubleshooting the valve. If the diagnostic lights are flashing identify the coded flash using the matrix found at the end of the instruction manual 102-145

Yes, but because the internal switch opens and closes the circuit when the valve is operating, a resistor will have to be installed across terminals #1 & #2 of the zone valve power head to maintain a continuous circuit. The thermostat uses the power from the 24volt transformer through a continuous zone valve circuit to power the thermostat. If this does not happen the program will be lost the first time the zone valve operates. The thermostat manufacturers are now supplying the required resistors in the package for use when a heat motor type Taco zone valve operator is used. This resistor is around 1000 ohms, .5 watts. Contact the thermostat manufacturer for the proper size.

There is an 8 step process on the instruction sheet reference #102-163. You have to turn the adjustment dial all the way to the left. Make sure all the valves are open, and calling for heat. Turn the valve’s indicator counterclockwise until you notice an increase in temperature out of the valve. Once you reach this point turn the indicator approximately one full turn clockwise to stop flow through the valve with all the zones open.

No, the materials of construction are meant for a closed loop system where the same water goes around and around in the system. Our 560-G2 and 5101-G2 are recommended for open systems.

The setting of the heat anticipator is based on the current draw of the connected zone valve wiring. A low current drawing valve requires a longer heater wire to create the same amount of heat. A high current draw circuit requires only a short heater wire.

For the first 1½ minutes, you will read 24 volts across terminals #1 and #2. The valve will have reached its operating stroke in that time. An internal switch will open the circuit to allow the heater to cool and control the length of stroke of the valve. When the circuit is opened, the load is taken off the transformer and the voltage jumps up to 28 volts. Once the valve gets into its cycle, there will be a current draw for 10 seconds and no current draw for 20 seconds.

Rated to 125 bar working pressure, this hose is ideal for larger lines after a regulator where higher flow rates and additional flexibility is required.

The rapid blinking light indicates the valve is charging. if the blinking light comes on while the capacitor control failure. You may have to replace the control.

Although, a minimum length is required on most circuit setters, the Accu-Flo does not require a minimum because of the differential across the fixed Venturi orifice with minimal turbulance and optimal accuracy.

The most likely cause of flow not going to the system is the boiler protection is engaged. Disconnect the power supply, and then disconnect the boiler return sensor from the valve. Reenergize the valve with 24 volts, and the valve will work normally. You must find an alternative way of protecting the boiler, if the return temperature will be less than the boiler manufacture recommends.

These correction factors are applied to the differential reading which is taken with a differential pressure gauge. The corrected reading is applied to the flow chart. If you have a formula that the differential is applied to, the correction is the square root of the difference in specific gravities of the flowing fluid, divided by the specific gravity of the standard fluid, water at 60°F. The viscosity does not affect the flow meter but can slow the flow due to the added resistance in the system.

Pressure Reducing Valves should always be installed in accordance with the manufacturers recommendations. In particular always insure; correct direction of flow, correct orientation, clear access for general maintenance and repairs. Pressure Reducing Valves can have various end connections such as flanged or threaded so installation will need to take this into account. Always ensure a pressure gauge is installed on the downstream side, to confirm set pressure. Always take into consideration the need for pressure relief or safety requirements downstream of the Pressure reducing valve. A safety valve may need to be installed and set at a suitable safe pressure to avoid over pressurisation events.

Normally, a check valve is noisy if the valve is oversized for the flow going through the valve. The flow cannot lift or swing the disk all the way open so the disk bangs back and forth within the body of the valve.

You can try adjusting the valve using the adjustment knob at the top of the valve. If the pressure continues to fluctuate, you could have a faulty expansion tank.

The Taco Zone Sentry Zone Valve could fail in the open position, which can raise the DHW temperature to the same temperature as the boiler water. The tempering valve will help protect against scalding if the valve fails in the open position.

No. Terminals #2 and #3 are only connected to a micro switch and there is no power across them. They are called dry contacts.

FlowCheckValve

This is a high head capacity valve typically used in high rise applications. The heavy duty construction allows this valve to operate at head pressures up to 150 ft. However, if the pump head is greater then the 150 ft, it will lift the seat and allow flow through. Check the pump head output, and throttle the flow down to reduce the differential head.

Typically, this is caused by debris accumulating on the disk or seat. This would be the case if the valve worked fine when it was first installed. You will have to take the valve apart and clean the seat, disk, and stem to bring the valve back to original. The stem should be vertical.

Process Systems stocks a wide range of pressure relief valves for different media including steam and fluid. These PRV's include both direct acting and pilot variants in threaded BSP and flanged configurations.

Remove the wire from the #1 terminal and apply an ohm meter across terminals #1 and #2. The meter should read 22 ohms +/- 1 ohm. If the meter needle doesn\’t move or the digital reads 0.L, the circuit is open or the internal contact of the internal leaf switch is dirty. If you get an ohm reading of 16 to 22 ohms, the circuit is good but there might be a failure of the heat motor. With the #1 wire removed from the operator for 5 minutes, you can twist the operator and remove it from the valve body. The replacement power head part number is 555-050RP. You don\’t have to change the whole valve and the operator can be removed without taking the pressure off the system. When you remove the power head, if you see a dark brown wax around the piston, then the diaphragm in the heat motor has failed.

In most cases a pressure reducing valve needs to be able to sense the resultant pressure downstream of the valve. This is most commonly measured against an opposing spring tension or pneumatic force, which is set during the commissioning of the valve. The balance of these forces encourages the opening and closing of the main valve. The most common type of Pressure reducing valve is a self-acting type. Where Self-Acting requires no external power or input They can satisfactorily perform, over a wide range of pressures and flow rates.

Drip Pan Sizing: Water Heater Diameter Up to 17.75 = min. 20″ pan 18″ – 23″ = minimum 24″ pan 24.5″ = minimum 26″ pan.

In some installations, code requires that no standing water (usually condensate) be present under the water heater. In those cases the condensate drain tube is placed under the dam so standing water can be diverted through the drain tube to a drain line. The dam is installed over the tube, so in the event of a failure the water would accumulate quicker then the flow through the tube and would be able to reach a level of 3/4″ in the pan, triggering the valve.

No, it is a 3 TERMINAL zone valve. One terminal of a 24 volt, 40VA transformer is wired to one side of the thermostat. The other side of the thermostat is wired to terminal # 1 of the zone valve operator. The #2 terminal of the zone valve operator goes back to the other terminal of the transformer. There is an end switch connected between terminal #2 & #3 of the zone valve operator. To activate the boiler control we run another wire from #2 terminal to one of the T terminal of the boiler control. We run another wire from the #3 terminal of the zone valve to the other T or TV terminal of the boiler control.

The 560 series valves are designed to be installed down-stream of a fan coil unit. The discharge of the fan-coil would be connected to the unit connection of the valve. A tee would be installed in the upstream side of the fan-coil supply line. The branch connection of the tee would be connected to the bypass connection of the valve. The main side of the valve would be connected to the return main of the system. The system fluid flows through the bypass connection to the return main when the valve is not energized and from the unit connection to the return main when the valve is energized. The bypass connection is not a positive shut off when the valve is energized.

If it’s a tankless heater application the coil may be fouled from high lime content in the water. Try using a lime X to clean the heat exchanger so the water passes through the coil easier. Fouling is typical when using a heat exchanger.

Normally, a check valve is noisy if the valve is oversize for the flow going through the valve. The flow velocity is not high enough and can not lift the disk all the way open so the weight bangs within the body of the valve.

The valves you have are 572-2 and 573-2 zone valves. There should be 3 terminals marked #1, #2 and #3. #1 and #2 should have 24 volts going to them when the thermostat is calling for heat. If you have 24 volts, the valve should open after 1½ minutes. If you don\’t have 24 volts, the problem is with the wiring, the thermostat, or the transformer. If other zones are operating off the same transformer and working fine, the problem isn\’t with the transformer. If you have 24V at #1 and #2, then it is internal to the operator.

Taco still offers a thermostat #568-20. It may not look like your original, but it functions the same. Many people mistakenly think the 571 zone valve is a 3-wire zone valve because it has 3 terminals. All the Taco 500 series zone valves are 2-wire, 3-terminal zone valves. The heat anticipator has no bearing on the operation of the zone valve. Its purpose is to trick the thermostat into shutting off ahead of time, allowing the heat left in the piping system to dissipate into the room and not overshoot the temperature setting. The current draw of the circuit had to be matched to the heat anticipator so it would work properly. A lot of the new thermostats do not require a heat anticipator. All of the battery operated thermostats will work with the resistor and the units that require a third wire (C) to get power from the transformer. It is the digital units that either steal power, need the resistor, direct power, or battery. All the other conventional units work, but make sure they handle a current rating of 1 Amp.
