Anderson Greenwood Reserve Capacity Relief Valve
Reserve Capacity Relief Valve
Designed to provide overpressure relief for large cryogenic storage volumes; enables emergency capacities protecting against adverse conditions.


  • Large orifice area reduces dramatically the number of valves needed to provide safety.
  • O-ring seat provides bubble-tight performance to 90% of set pressure.
  • A combination of tension link and spring force holds the valve closed to provide positive opening at set pressure and bubble tight shut-off at reseat.
  • Full open at set pressure with no overpressure required for rated capacity.
  • Flange mounting with a flat face, smooth finish.
  • Reseat pressure is 50% of set.
