Your benefits

  • Hygienic Design: This ensures safe use especially in hygienically critical processes, e.g. in the food, beverage and pharmaceuticals industry.
  • Safety: The double guided valve rod of the safety relief valve guarantees reproducible functional behaviour even in critical operating conditions.
  • Economic efficiency: The optimized, divided valve disc design allows a simple and inexpensive on-site sealing replacement.
  • Time savings: The optional pneumatic venting allows easy integration of the safety relief valve in a fully-automated cleaning cycle (CIP, SIP).
  • Flexibility: A variety of connection options allows adaptation to different customer requirements.
  • Productivity: The option of a housing heating allows use of the safety relief valves even in cold environment, or securing cold-solidifying processes.
