RS PRO Stainless Steel Single Non-Return Valve 1/2 in BSP


The RS PRO single non-return valve is ideal for controlling the flow of water and steam in heating and cooling systems. It's made from stainless-steel construction and has a simple, compact design. With a maximum operating temperature of +220ºC and maximum working pressure of 25 bar, the valve can withstand higher pressures and temperatures than brass alternatives.

Simple to install, this disk check valve has female screw connectors with a 1/2-inch BSP (British Standard Pipe) thread. As the valve is fitted with a spring, it can be installed either horizontally or vertically.

This non-return valve conforms to US and European ANSI/ESD S20.20:2014 and BS EN 61340-5-1:2007 standards for electrostatic control and has a CE (European Conformity) rating of PN25 for pressure. Non-return valves prevent the reverse flow of fluids and gases within domestic and industrial pipeline systems.
