M22 × 1.25 Ball Check Valve
Gas / LPG cylinder valve
A ball-and-spring check valve insert for gas and LPG cylinders. It has a male M22 × 1.25 thread, a female M16 × 1.5 inlet, and is offered in two material versions that look the same from the outside.
This valve is a compact insert for gas and LPG cylinders. A steel ball and spring sit inside the body, and the nose has side ports. Two material versions are available. The solid brass version is supplied with a copper sealing washer. The stainless-steel version is copper-plated so that it looks the same as the brass valve; the underlying steel colour can be seen at the nose, and it is supplied with an aluminium sealing washer. Pricing of the plated steel version is more stable. Working pressure, applicable standards, certificates, model numbers and minimum order quantities are available on request.
