High Efficiency Valves

High Efficiency Valves

Pilot operated safety valves and supplementary loading systems for optimal tightness right up to set pressure.

ADVANTAGES

  • Pilot Operated Safety Valve:
  • Piping between the pilot and main valves is integrated into the cover to prevent damage and freezing
  • Integrated Backflow Preventer as standard part
  • Four week delivery time from the factory
  • Higher capacity than comparable size with extra orifices
  • 20% less installation space than competitors’ comparable models
  • Supplementary Loading System:
  • Higher operating pressures are possible
  • Closing pressure difference of up to -3 %; opening process is independent of back pressure
  • Functional test and valve adjustment possible during operation
  • Max. 0.1 sec. for valve to open completely
