Series 652

This safety valve made of gunmetal is an economical alternative to high-performance safety valves, in cases where only small blow-off capacities are required. The version 652mFK for neutral liquids is ideal for the protection of pumps and pressure vessel systems, in cases where boiling point is never reached or if no evaporation of the media can occur. A diaphragm protects the moving parts and compression spring against the Media. The version without diaphragm, type 652sGK is ideal for protecting small compressed air systems.

Depending on the sealing material, this valve can be used for neutral, non-toxic compressible media with varying temperatures. Fitted with an EPDM seal, this can be used for steam boilers with a volume of less than 10 liters up to a set pressure of 3 bar.
