Pressure Reducing Valves

Pressure Reducing Valves for Safe, Efficient Fluid System Control

Pressure reducing valves (PRVs) automatically lower incoming pressure to a safe, stable level. In doing so, they protect downstream equipment, extend system life, and keep operations running smoothly. You'll find pressure reducing valves in water distribution networks, heating and cooling systems, industrial plants, and compressed air networks where consistent outlet pressure matters.

In addition, this collection brings together PRVs in brass, stainless steel, bronze, and engineered plastics, covering a wide range of sizes, designs, and pressure ratings for domestic, commercial, and industrial use. If you also need shut-off control, see our ball valves collection.

Key Benefits of PRVs

• Automatic pressure regulation — reduces high inlet pressure to a steady outlet level regardless of supply fluctuations
• Equipment protection — guards appliances, pumps, and pipework against damage from excess pressure
• Improved safety — keeps pressure at safe operating levels, reducing the risk of leaks, bursts, and failures
• Energy efficiency — stabilising pressure lowers unnecessary strain on pumps and cuts operating costs
• Long service life — brass and stainless steel construction resists corrosion, wear, and high temperatures
• Consistent system performance — stable pressure extends equipment life and reduces long-term maintenance costs

How Pressure Reducing Valves Work

A PRV uses an internal spring-loaded diaphragm to sense outlet pressure and adjust the valve opening accordingly. When inlet pressure rises, the diaphragm closes the valve slightly to maintain the set outlet level. As a result, downstream equipment receives a consistent, controlled supply regardless of mains fluctuations. Furthermore, most pressure reducing valves include an adjustable set-point, making them straightforward to commission on site. For further technical guidance, refer to the BSRIA guidelines on hydraulic system design.

Where Pressure Reducing Valves Are Used

In domestic water supply, PRVs protect plumbing fixtures and appliances from high mains pressure. Consequently, showers, taps, and household systems receive a consistent, reliable flow. Similarly, in commercial and industrial settings, PRVs serve heating and cooling circuits, compressed air networks, process pipework, and utility systems where stable pressure is critical for safety.
