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.
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.
