Tight Shut-off Easy Installation Leak Detection Low Seat Leakage • Gas or Liquid Service • Inline Maintenance • NACE Capability The Type P1 Control Valve is versatile and can be used for on/off or throttling service. 19 Spring ranges from 3-15 psi to 30-60 psi. The valve can be used in corrosive or noncorrosive gases or liquids, limited by available compatible materials. Maintenance on the valve can be accomplished without removing the valve body from the line (pressure must be removed and the valve isolated before attempting.) A vent is provided in the valve actuator to detect leakage of actuator stem seals. Our composition disc assembly and seat offer positive shutoff at maximum body working pressure. NACE construction materials are standard for the steel body valve only, and comply with the National Association of Corrosion Engineers MR0175. Applications • On-Off or Throttling Control • Heater Fuel Valve Control • Gas Distribution Disk Holder Assembly Orifice Diaphragm O-rings Stem Wiper Adjusting Screw Spring Maximum Pressure Drop Maximum Housing Pressure For all port diameters 150 PSIG Spring Ranges See Table With Nitrile Seat / Diaphragm -20 to 170˚F Material Temperature Capabilities Units with a Steel Body selection will automatically be provided with internal parts conforming to NACE MR 0175.
