These low pressure regulators with OPSO safety valve are mainly dedicated to meter box installations. They can be used with Natural Gas, LPG (butane, propane and their mixture) or other non-aggressive gases (air, nitrogen,…). Regulator is equipped with double inlet and double outlet . The plug, factory fitted on one of these inlets and outlets, can be unscrewed and moved so as to achieve the desired geometry.
Features
OPSO: OPSO safety stops the gas flow when the regulated pressure is higher than a defined value. Easy resetting: cap rotation allows pressure balancing before complete resetting. Visual indicator displays open-close state. Sealing wire (optional). It can be provided.
UPSO: UPSO safety stops the gas flow when the regulated pressure is lower than a defined value. Push button easy resetting, independent from OPSO resetting. Optional.
PRV: Pressure relief valve. Some models are equipped with a limited capacity pressure relief valve (LRV) which discharges thermal expansion over pressures and avoids any unnecessary OPSO triggering. Optional.
Vent: The vent can be connected to a pipe (to be used when the regulator is installed in a not ventilated or safe area).
Test Point: A “hose” type test point allows controlling the regulated pressure. Optional.
