High-alloy stainless steel safety valves for demanding applications

Our high-alloy stainless steel safety valves offer outstanding advantages and versatile application options, especially where safety valves made of gunmetal reach their performance limits. These valves are ideal for industrial applications that require the highest safety standards.

Thanks to the high flexibility of the designs, the optimum configuration can be provided for every application. In addition to the basic version, a wide range of sealing variants and materials are available that can be individually adapted. The back pressure-compensating bellows valves with robust metal bellows and the optional gas-tight bonnet provide the necessary special features to meet the highest safety standards.

Our stainless steel safety valves are a robust and versatile solution for demanding industrial requirements and offer reliable performance even under difficult conditions.

connection types
  • Flange connection
  • steam boilers and steam plants
  • pressure tanks and pressure systems
