Gun Metal Gate Valve Compression x Compression 35mm to 54mm

On large copper mains, a Gun Metal Gate Valve Compression x Compression gives full-bore isolation without any soldering. Gunmetal is a bronze alloy that stands up well to water, and compression x compression means Compression at both ends, so the valve fits straight onto copper pipe with nuts and olives.

Using a Gun Metal Gate Valve Compression x Compression

With the wedge raised clear of the bore, flow is barely restricted. That suits rising mains, plant room headers, tank outlets and commercial supply pipework. The 35mm, 42mm and 54mm sizes are for the bigger services you find in tenement blocks, schools and commercial buildings.

Support the pipe on both sides, because a valve this size has real weight. Tighten each nut while holding the valve body. Turn the wheel fully open or fully closed, and do not use it to regulate flow. A part-open gate vibrates and wears the seat, so a different valve is needed for balancing.

Smaller gate and lockshield valves are also listed in Valves & Control Devices.

Common Questions

Why gunmetal on a big gate valve?

Gunmetal is a bronze that copes well with water and resists dezincification, so the body lasts on mains and plant room pipework.

Can this gate valve be used on gas?

No. A water gate valve is not approved for gas. Gas isolation needs a valve made and marked for gas, fitted by a Gas Safe engineer.

Will the 54mm valve fit imperial pipe?

It is made for metric copper. Old 2 inch copper is close but not always a match, so measure the outside of the pipe and use an adaptor olive if needed.
