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

Offering the highest flow capacity in the L182 screwed WRAS range, the 24mm orifice and Kv 12m³/hr make this valve ideal for larger potable water installations, commercial plant and industrial process systems where dependable high flow performance is required. Its low 0.35 Bar minimum operating pressure ensures reliable operation even where differential pressure is limited.

Why would an engineer choose this size?

With a Kv of 12m³/hr, the 1" WRAS valve is ideal where higher flow rates are required without moving to the larger L182D-BIG Series. For 1¼" to 2" pipework and maximum flow capacity, see the L182D-BIG WRAS approved range.
