Import Bronze Relief Valve — Buy in Bulk from Supplier in India

The Bronze Relief Valve from Leader Valves Limited is a straight-type, open discharge pressure control device rated for a maximum working pressure of 10.34 bar in water or air applications. It is manufactured from bronze and features screwed male ends to BS:21, with an item code of BM000014 and a standard size of 15mm, though the model range extends from 15mm to 80mm. This valve is designed to relieve excess pressure by discharging fluid directly to atmosphere, protecting downstream equipment from pressure spikes that could cause catastrophic failure.

Bronze as a valve body material offers inherent resistance to dezincification and seawater corrosion, which makes it a standard choice for marine, plumbing, and general industrial services where ferrous alloys would degrade. The BS:21 thread standard specifies a Whitworth parallel thread form, ensuring compatibility with legacy British and Commonwealth piping systems still prevalent in many Commonwealth markets. The open discharge configuration means the valve vents to atmosphere rather than into a closed return line, a distinction that simplifies installation but requires careful positioning away from personnel and electrical equipment. The 10.34 bar rating sits within the low-to-medium pressure range typical for building services and small-bore process applications rather than heavy industrial boiler protection.

Buyers for this valve include ship chandlers, municipal water authorities, HVAC contractors, and industrial maintenance departments across Commonwealth markets. The 15mm to 80mm size range covers domestic plumbing through to light commercial pipework, with the smaller sizes most commonly stocked for replacement and repair. When sourcing from Leader Valves Limited in India, buyers should confirm the exact alloy specification (typically青铜 alloys such as LG2 or G-CuSn10Zn per EN 1982), pressure test certificates, and conformance to any local water contact regulations. The valve is suitable for water and air service, but steam or aggressive chemical applications require verification of wetted material compatibility with the supplier.
