Water Pressure Reducing Valve, Low Lead Bronze, 25 to 75 psi
Wilkins water pressure reducing valves are designed for controlling high inlet pressures and then bringing down to a lower value (25 - 75 PSI); ideal for industrial water lines and commercial irrigation systems. They feature a balanced piston design enabling the regulator to respond to changes in the system flow demands and a direct-acting by-pass facility to prevent excessive pressure build-up caused by thermal expansion. These low-lead valves can be installed in any position and are certified for use in potable water applications. Choose from a wide range of these products available in pipe sizes ranging between 3/4 & 3 inches on Raptor Supplies.

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.
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.
Do water pressure reducing valves restrict water flow?
Yes, water pressure reducing valves restrict the flow of water to some extent as they regulate the pressure. However, they are designed to maintain a steady and consistent flow while reducing the pressure.
Are water pressure reducing valves maintenance-free?
While water pressure reducing valves generally require low-maintenance, it is recommended to have them inspected periodically. Sediment or debris in the water supply can affect the valve's operation, so it is important to clean or flush the valve if necessary. Additionally, the diaphragm or piston inside the valve may wear out over time and require replacement.
Where should a water pressure reducing valve be installed?
They are installed near the point of entry of the water supply, such as the main water line entering a building. This ensures that all water flowing into the plumbing system is regulated and the pressure is reduced uniformly throughout.
How do I know if I need a water pressure reducing valve?
Signs that you may need a pressure reducing valve include excessively high water pressure, frequent leaks or bursts in your plumbing system, banging noises in pipes and inconsistent water flow.
Why are water pressure reducing valves necessary?
Water pressure reducing valves are necessary when the incoming water pressure from the municipal supply is too high. High water pressure can damage pipes, fixtures and appliances, leading to leaks, bursts and other plumbing issues. These valves regulate and reduce the pressure to a safe and manageable level, protecting your plumbing system.
Can water pressure reducing valves help conserve water?
Water pressure reducing valves can indirectly contribute to water conservation efforts. By reducing the water pressure to a more appropriate level, they can prevent wasteful water usage due to excessive pressure. Additionally, regulated pressure can improve the efficiency of fixtures and appliances, reducing water consumption.
