PressureRegulating Valve for water

2pcs 1/2 Pressure Reducing Valves Safety Valves Pressure Relief Valves This is a pressure reducing valve, which is made of good quality copper material, sturdy for long lasting use. You can install and remove this pressure relief conveniently and easily. This is suitable for solar water heater, electric water heater, gas water heater, heat pump water heater, etc.

Effectiveness of the Thermal Expansion by-pass featureis limited to systems where the street main pressure is less than the setting of the heater relief valve. Therefore, the highest allowable pressure setting for the relief valve should be selected for widest effectiveness of a Thermal Expansion by-pass

Pressureregulating valve

The use of a water pressure-reducing valve normally creates a closed system. When water is heated in a closed system, it expands, causing an increase in pressure. This pressure may increase to the set pressure of the relief valve (on the water heater) causing it to drip, thus releasing the expanding water and protecting the system against excessive pressure, This increase in the system pressure over that regulated by the reducing valve is called "thermal expansion pressure".

No. 25AUB by-pass Model water pressure reducing valves, are an economical solution of this annoyance, since under certain conditions it allows the expanding water to escape back into the supply main before it can affect the relief valve.

Annual inspection of all water system safety and control valves is required and necessary. Regular inspection, testing and cleaning assures maximum life and proper product function.

For household use install the reducing valve when possible, so that the sill cock line is on the high or street side of the reducing valve. Before installing the reducing valve, flush out the line to remove loose dirt and scale, which might damage valve disc and seat. On valves having strainers the screen should be removed and cleaned at least once every six months, more often if water conditions are bad.

INSTALL VALVE IN THE LINE SUPPLY PRESSURE CONNECTED TO THE "IN" CONNECTION. These regulators can be installed horizontally in either an upright or inverted position or in a vertical position, and must be installed in an accessible location to facilitate servicing the regulator.

When high house pressure is evident, open a cold water faucet. If your pressure gauge shows immediate drop to the regulated reduced pressure setting it indicates the regulator is operating correctly end that thermal-expansion is the cause of the expanded pressure.
