Pressure reducing vlves (with check vlve) X()G, XGL 3- Pressure ontrol Vlves unctionl Symbols XG XGL X XG X Vlve is used to set pressure in brnch circuit lower thn pressure of the circuit. y connecting remote control vlve (GR-, -7, etc.) to vent port, brnch circuit pressure cn be set remotely. Reducing vlve with check vlve will llow free flow from the reduced pressure circuit to circuit.
