Types 1301F and 1301G regulators are self-operated, high-pressure regulators, which can be used where high pressure gas must be reduced for use as pilot supply pressure in pilot-operated regulators or as loading pressure in pressure-loaded regulators. Types 1301F and 1301G regulators can also be used in many other applications as high-pressure reducing regulators for various gases. Type 1301F regulator provides outlet pressures to 225 psig / 15,5 bar in three spring ranges. Type 1301G regulator provides outlet pressures to 500 psig / 34,5 bar in one spring range.
