Specifications: 0-40 PSI Adjustable Max Inlet Pressure Inlet Connection: POL - Outlet Connection: Barb Gauge Port: 1/4” FNPT 3/8” Hose Exterior Finish: Red Wet Coat Diaphragm Our High Pressure Regulator are regulators that meet a variety of applications for liquid or vapor service. The compact body design makes these regulators particularly useful in installations with space limitations. The regulators come equipped with a handwheel adjustment. These Regulators are listed as high pressure, non-relief regulators. The regulators contain brass materials that are not compatible with anhydrous ammonia service. OPERATION: The regulator is a high capacity, pounds to pounds, industrial gas regulator.The maximum output pressure is 40 PSI. This regulator is not intended for use in pressure applications below 3 PSIG. The operating temperature range is -40° to +200° F. All personnel installing this device should be trained on the hazards associated with combustible gases and fluids. We assumes no responsibly from damage or injury that may result from servicing or the improper installation of this regulator. OPERATION: The regulator is a high capacity, pounds to pounds, industrial gas regulator. The maximum supply pressure is 250 PSIG. The maximum output pressure is printed on the regulator nameplate. This regulator is not intended for use in pressure applications below 3 PSIG. The operating temperature range is -40° to +200° F. CAUTION: The regulator is a non-relieving regulator and thus cannot exhaust excess pressure at the regulator. In order to establish an accurate output pressure it may be necessary to cycle the downstream flow or to set the regulator at a slight flow.
