Pressure Reducing Valve

A pressure reducing valve (PRV) automatically lowers a high or variable inlet water pressure to a lower, stable outlet pressure. It uses a spring-loaded diaphragm or piston to maintain the downstream setting, protecting household fixtures, appliances, and pipework from excessive pressure.

⚠️ Note: Set outlet pressure to system requirements and fit upstream strainer where debris is likely; a thermal expansion provision may be required downstream on closed systems.

Applications

Installed at the main water entry or ahead of sensitive appliances and floors in tall buildings to keep household pressure within a safe, comfortable range and reduce noise, leaks, and wear.

FAQ

Why install a pressure reducing valve?
High incoming pressure can stress pipes, joints, and appliances and cause noise or leaks; many plumbing codes recommend or require pressure reduction above a threshold (often around 5–5.5 bar / 80 psi). Confirm the local code requirement.
Should a PRV be installed with a strainer?
A strainer upstream helps protect the valve seat from debris that can cause it to stick or leak. Some PRVs include an integral strainer; otherwise fit one ahead of the valve.
