2 Piece Wras Approved Elomatic Full Bore Valves

WRAS (Water Regulations Advisory Scheme) approval means the valves meet regulatory standards for use in potable water systems in the UK. WRAS tests for materials, construction and performance.

Common materials are dezincification resistant brass or stainless steel. WRAS has requirements for leachable lead and other substances that could contaminate drinking water.

2-piece valves have the body and ball as one part, with the stem as the second part. This makes them more compact but non-serviceable. 3-piece valves can be disassembled for servicing.

Typical end connections are copper tube connectors, compression fittings and push-fit connectors. Threaded BSP or NPT connections are also sometimes used.

Common handles are cross type lever handles, tee handles and round knobs. Locking handles are also available to prevent tampering. Extended handles allow ease of operation in tight spaces.

Most 2-piece WRAS approved valves have pressure ratings of up to 400 psi (27 bar) and temperatures up to 230°F (110°C), with some high pressure models rated beyond this. Always confirm ratings for your application.

Many have full or near full-port openings to minimise flow restriction. Actual flow depends on valve size - 1/2” to 2" are common sizes for plumbing uses.

Typical applications are water supply lines, sinks, toilets, water heaters, washing machines, dishwashers and other household water control.

No special maintenance is required, just periodic inspection for leaks and smooth operation. Replacement is needed if a valve fails.

Most come with manufacturer warranties from 3-10 years depending on materials and brand. Some offer extended warranties against leaking.
