1.) Select a size , 2.) Select a spring range, 3.) Since the Body contains the pressure, select the proper material that is suitable for the fluid or gas used. 4.) The Spring chamber, spring hardware and the adjusting spring are isolated (non-wetted) from the fluid media and should be selected based on the external environment the valve is exposed to. The carbon steel spring chamber, when selected, is painted on the exterior and interior to withstand normal atmospheric corrosion. Unless specially ordered, the adjusting spring is always a high strength chrome silicon spring steel which is completely protected inside the enclosed spring chamber. After the customized selection is made, click to continue, and instructions will be provided to either print or save the selection or to proceed with ordering the item on line. Printing the selection will not commit one to ordering the items selected. Should you have any questions on the product capability or product options, or are having difficulty in making the pricing selections or ordering, please contact us by e-mail or phone between 9AM-5PM Eastern time, Monday-Friday.

If your burner doesn’t shut off when you open the blowdown valve, or if it doesn’t restart when your water level returns to normal, contact our service department immediately. We’ll send a technician over right away to get you fixed up and operating safely.

PressureReducing Valve

Designed for clean, filtered or strained, non-abrasive liquid service: oils, lubricants, greases, solvents, and most non-fluorinated chemicals compatible with Teflon PTFE seals. Valve is piston-operated, metal-seated without any elastomers. Do not use for extended shutoff service or for extremely low flows (less than  5% of maximum capacity, approximately). Values below the low limit of the spring ranges shown below can be achieved if the flow rates are substantially higher than the minimum 5% of maximum rated capacity. To be on the safe side, a relief or bypass valve should always be installed on the outlet side of the regulator (not included with valve). For outlet pressures below the ranges stated below, request model PRH09-FLG double piston model, that is specifically designed to handle the lower outlet pressures that the PRH04-FLG cannot handle. Do not use with liquids that tend to crystallize or solidify under operating conditions. Not for use on steam service as operating temperatures can easily exceed the limitations of the Teflon seals which are rated for 400 Deg F max. Consult factory for steam & gas service. The balanced piston design of this model accommodates large variations in inlet pressure. When ordered, if a set pressure is not specified, valves are set to the minimum pressure setting for the range selected. Valve can operate in any orientation: vertical, horizontal, etc. A high-pressure filter or strainer, which should be no coarser than #60 mesh, can be ordered from Stra-Val. See model SBS-10.

A more thorough way to test your water cutoff safety, though, is with a Slow Low Cutoff Test. This test better reflects the real-world conditions under which a cutoff safety would operate. To perform the test, your burner needs to be set at 50% or lower. Instead of opening the blowdown valve to force a rapid low-water situation, you are going to turn off the feedwater pump. Once the supply of feedwater stops, the boiler will begin converting all the remaining water to steam, and the water level will slowly drop since no feedwater is replenishing the boiler.

Regulating valve

Note: Dimensions are approximate and are subject to change without notice. Request certified dimensions before final product installation.

This valve operates with a compression spring acting on the main valve which is used to adjust the outlet pressure with an adjusting screw. The reduced outlet pressure is very easily adjusted in the field. To increase outlet pressure, simply loosen adjusting screw lock nut (2) to increase spring compression by turning the adjusting screw (1) inward. Similarly, to get a lowering in outlet pressure requires a reduction in spring compression by turning the screw outward. A pressure gauge is required on the outlet side of the regulator somewhere in the downstream piping close to the valve, to monitor the result while making the adjustment. The valve will operate in a vertical orientation as illustrated, horizontal, or any other orientation.

Waterpressureregulator

To perform a standard low-water test, your boiler needs to be set at a reduced firing rate (50% or lower). Then, simply open the low-water cutoff blowdown valve and monitor the sight glass to make sure the water is draining rapidly. As the water level drops, the low-water cutoff safety should engage, and the burner should shut off. If it does, then simply close the valve and let the water level build back up until the burner restarts.

Both situations can be remedied by our skilled service technicians. Remember, no matter what your boiler needs, WARE is standing by to help.

Watch the water level at the sight glass. When the water level gets low, the burner should shut off. If during this test the water level falls below the level of the sight glass and the burner is still firing, your system has not passed the test. In this situation, you should immediately restart the feedwater pump, shut down the boiler, and contact WARE for an evaluation. Chances are, you either have:

24 Jan 2023 — A fluid-based system (hydronic) offers better comfort and efficiency than resistance mats. But it requires careful planning and professional installation.

WARE is an industrial & commercial boiler rental and service company that specializes in sales, service, valve repair, rentals, parts, turn key and boiler training.

In a properly-working boiler, a low water level should trigger a shutdown of the burner system. That’s a good thing, because if your boiler keeps firing without enough water in it, it becomes an extreme risk to life and property. Checking your low-water cutoff regularly is extremely important. There are two ways to do it.
