RG873V HIGH PRESSURE REGULATOR • Precise pressure control Up to 1000 psig control with GP series control valves 0-6000 psig control as a stand alone Excellent stability Relieving capability The model RG873V is a Piston type dome-loading regulator. It utilizes a balanced poppet design for high flow and minimum effect of inlet pressure on outlet pressure. The poppet assembly is contained in a cartridge with internal filtration for easy in field changing. The regulator is self-venting. PERFORMANCE • Type • Maximum Inlet pressure RG873V RG873V-02 Outlet pressure RG873V RG873V-02 Outlet pressure is adjusted by applying pressure to the dome port. When reducing the pressure the regulator will self vent via the vent hole near the cap. This is normal. When reducing set pressure, reduce pressure to below the new setting then increase pressure to the new setting. Typically a Proportion Air electro-pneumatic control valve pilots the regulator with the desired pressure.
