Piloted Safety Valve
 

Main advantages of GUICHON VALVES’s piloted relief valves :

  • Good tightness : the tightness is maintained until 98 % of the set pressure
  • Quick opening : the useful overpressure to obtain full opening is lower than 3%
  • Modulating operation : opening proportional to the overflow, therefore no throttling or pumping
  • Stable operation : no adjustment or setting required on site
  • Easy maintenance : elastomere seals, removable seat and top entry design for easy and quick intervention, disassembly not required, no special tools
  • Factory adjusted pilot : no adjustment or setting required on site.

Main options :

  • Separate feeding for fluids with hard particles
  • Remote control
  • Site setting check
  • Filter
  • Opening indicator
  • Clutching lever on the pilot
  • Remote pressure connection
  • Connected pilot exhaust
  • Manual pilot locking.
