Water Pressure Reducing Valves

Raptor Supplies offers a wide range of water pressure reducing valves or regulators designed to control the influx of water supply pressure and reduce it, from brands like Apollo, Watts, Bell & Gossett, Taco, Wilkins and Cash Acme. These water pressure reducing valves are ideal for house plumbing lines, pipe fittings and low pressure pipelines. Apollo 36ELF, 36H, 36 HLF and 36LF Series valves feature low lead or lead free bronze construction with a stainless-steel adjusting screw and dielectric cage for superior corrosion resistance. The pressure ranges between 15 and 75 PSI. These Apollo valves have FNPT connections and are designed according to ASSE and CSA standards for ensuring reliable operation. They are available in 1/2 inch to 3 inch pipe sizes. Watts offers pressure reducing valves in iron, bronze, lead free brass, lead free copper and lead free copper silicon variants for valves with pressure ranging between 3 and 140 PSI. 152A Series steam pressure regulators by Watts are used in oil lines, autoclaves, steam irons and single radiators. These steam regulators provide highly sensitive pressure response with minimal pressure drop. These 152A Series valves feature FNPT threaded inlet and outlet ports for pipe sizes up to 1 inch in diameter.

Working Mechanism

  • Locate the water pressure reducing valve. It is installed near the main water line where it enters the building.
  • Identify the adjustment mechanism on the valve. It is usually a screw or a knob located on top or at the side of the valve.
  • Using a screwdriver or wrench, turn the adjustment screw or knob clockwise to increase the outlet pressure or counterclockwise to decrease it.
  • Make small adjustments and periodically check the outlet pressure using a pressure gauge.
  • Once you have set the desired outlet pressure, ensure that the adjustment mechanism is securely tightened to prevent unintentional changes.

Features

Wilkins Water Pressure Reducing Valves:

  • They control high inlet pressures and then bring them down to a lower value (25 - 75 PSI).
  • These valves feature a direct-acting integral by-pass facility to prevent excessive pressure build-up caused by thermal expansion.
  • They are made of low-lead bronze and are useful in potable water applications.

Apollo 36ELF Series Valves:

  • They feature a balanced piston design enabling the regulator to respond to changes quickly in the system flow demands.
  • These valves have a built-in thermal expansion bypass to prevent any reverse flow of water back into the system mains.
  • Their dezincification-resistant bronze body, stainless steel adjusting screw and dielectric polymer cage provide optimum corrosion resistance.

Watts LFN45B-EZ Series Valves:

  • Their standard bypass feature allows the water to flow back through the valve into the main when pressures exceed the pressure in the main supply.
  • These water pressure reducing valves feature lead-free cast copper silicon alloy construction that can handle temperatures within the range of 33 to 180 degrees F.

Frequently Asked Questions

What are the benefits of using a water pressure reducing valve in irrigation systems?

Installing water pressure reducing valves in an irrigation system offers several benefits. They maintain optimal water pressure, preventing damage to sprinklers, emitters and other irrigation components. Additionally, they ensure uniform water distribution and reduce the risk of excessive water consumption. PRVs in irrigation systems also extend the lifespan of the system by minimising the strain on pipes and reducing the potential for leaks.

Can a water pressure reducing valve eliminate the water hammer?

Water hammer is a hydraulic shock that occurs when water flow is suddenly halted or changed in direction, resulting in loud banging noises in pipes. While water pressure reducing valves can mitigate water hammer to some extent by regulating the pressure. Additional measures, such as installing check and foot valves may be required to effectively control the water hammer.
