757069 – SAFETY VALVE DIN CAST STEEL, FULL LIFT ANGLE 567N 150X250MM

IMPA 757069 – SAFETY VALVE DIN CAST STEEL, FULL LIFT ANGLE 567N 150X250MM – These valves 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%).
