Check Valve Valan-15CO

These valves are connected between the discharge hose and the manifold, allows the gas flow in one direction only, from the hose to the manifold, not in the other way.

The valves prevent gas escaping from the piping system during a discharge (except, of course, into the protected hazard area), should a cylinder not be connected to the manifold. They are supplied from the factory screwed onto the manifold.
