Product Description

 A valve that reduces high upstream pressure to a safer, lower downstream pressure

D&R Adjustable Brass Pressure Reducing Valve DN80, 1–6 Bar Compensated Piston PRV,

Female Thread Water Pressure Regulator for Residential & Commercial Plumbing

Function

Pressure reducing valve is a device that lowers and stabilizes downstream pressure according to the set upstream pressure.

When water enters from a public supply system with excessively high or unstable pressure, the pressure reducing valve ensures a stable and safe downstream pressure.

Fluctuations in upstream pressure will not affect the downstream pressure. Within the adjustable range of the valve, the operator can set the downstream pressure to the desired value.

Factory preset: 3 bar

Applications

Pressure reducing valves are used in water supply systems, heating systems, compressed air systems, and inert gas systems. They are suitable for hot/cold water, compressed air, and inert gases.

Recommended Installation Layout

To ensure stable outlet pressure, protect internal components, and extend the overall lifespan of the

Pressure Reducing Valve (PRV),

we recommend installing it together with the following components in sequence:

Flow Direction → Ball Valve → Strainer Valve → Pressure Reducing Valve → Check Valve → Ball Valve

These valves must be installed in accordance with proper pipeline installation standards and considered an integral part of the overall system.
