WRAS Approval

This valve is fitted with WRAS approved EPDM sealing materials and forms part of WRAS Approval Certificate No. 250702716 for use with products complying with the Water Supply (Water Fittings) Regulations across England, Scotland, Wales and Northern Ireland. Approval valid until 31 July 2030.

Additional Information

The combination of a low 0.35 Bar minimum operating pressure, full port diaphragm design and high temperature EPDM seals makes this valve an excellent choice for potable water systems, commercial heating installations and industrial water applications where reliable long-life operation is essential. The larger 18mm orifice and higher flow capacity make this model particularly well suited to applications requiring increased water throughput whilst maintaining dependable shut-off performance.

Why would an engineer choose this size?

The larger 18mm orifice and Kv of 5m³/hr provide significantly higher flow than the smaller models, making this 3/4" WRAS valve well suited to washdown systems, water treatment equipment and commercial plant installations.

Thanks for shipping me WRAS approved potable drinking water solenoid valves so quickly. You have great stock and price too. I must say your solenoid valve store is a dream to work with and supported with excellent customer service too. Valve is fitted and working a treat, I'll need some more later probably in 1/2" without WRAS approval for our tank feed system on 24vdc this time, so I'll be back soon. Thanks again. Si.
