Low-Pressure Safety Valve


Ritcher offers Low-Pressure Safety Valve which is designed for use with corrosive and pure liquids, gases and vapours. This valve can be installed as an angle valve on a vessel or as an inline valve in a pipe.

  • Set pressure: +20 mbar to +120 mbar (+0.3 psi to +1.7 psi)
  • Set vacuum: -20 mbar to -120 mbar (-0.3 psi to -1.7 psi)
  • Weights can be varied in 5, 10 and 20 mbar (0.07, 0.15 and 0.30 psi) increments
  • Stainless steel core in guide ensures dimensional stability even at high temperatures

  • The set pressure can be adapted to suit subsequent changes in operating parameters by the addition/removal of weights
  • The LPV is gas and liquid-tight to DIN EN 12266-1, bubble-tight
  • Compromise solutions, e.g. ball check valves, are not necessary
  • Direct-acting, weight-loaded
  • Proportional opening characteristic
