Reliance Valves Pressure Reducing Valves (PRVs) prevent damage to heating systems, appliances and buildings by reducing high inlet pressures from the mains water supply to a safer lower outlet pressure.

Pressure reducing valveworking principle

Designed for use in health hazard cross connections and continuous pressure applications where the water enters the equipment at or below its flood rim. Provides protection against backsiphonage incidents only. Applications include irrigation systems, firelines, and industrial process water systems.

Our extensive range of Pressure Reducing Valves effectively control pressure and flow rates across domestic, commercial and industrial buildings. From compact solutions for tight spaces, to larger high-performance designs and single-piece cartridges for easier serving and maintenance, we offer you a range of options to suit your specific pressure reducing valve application and installation requirements.
