757003 – SAFETY VALVE DIN BRASS SCREWED, W/RENEWABLE DISC RING 517 1″

IMPA 757003 – SAFETY VALVE DIN BRASS SCREWED, W/RENEWABLE DISC RING 517 1″ – These valves can be used both for vapours and gases, i.e. compressible fluids, and for liquids, i.e. incompressible fluids. Can be used for both types of fluid without changing their internal components. Entering of dirt should be prevented. Heavy shocks have to be avoided as well, because these can damage the disc and the seat. In order to prevent a safety valve from relieving too soon, it is necessary to maintain enough differential pressure between the set pressure and the working pressure (10%).
