PILOT PRESSURE REGULATOR 1/4" NPT Inlet 400 Psig (27.6 Bar) Description Generant Series PR, Pilot Pressure Regulators are balanced, relieving regulators ideally suited for providing a reliable, constant pilot pressure to a Pilot Operated / Dome Loaded regulator. The balanced design allows for a consistent, regulated downstream pressure regardless of fluctuations in inlet pressure. The relieving function allows the regulator to vent when adjustments are made without the need for bleeding pressure from the pilot circuit. Materials of construction allow for compatibility with most gases. The Series PR can be ordered Cleaned & Packaged for Oxygen Service. Features • Balanced Design to Minimize Outlet Pressure Fluctuations upon Changing Inlet Pressure • Relieving Design Suitable for Pilot Pressure Applications • Optimized spring performance and patented Venturi tube provides high flow rates with low droop • Easily cleanable by removing bottom plug • Optional Plastic knob and Panel Mounting Configurations Technical Data Maximum Inlet Pressure: 400 Psig (27.6 Bar) Effect of Inlet Pressure Variation: < 1.0 PSI / 100 PSI Temperature Range: -20 to 200 °F (-30 to 95 °C) Pressure Ranges Spring Outlet Pressure Code Range PSI (bar) A 0 - 50 (0-3.4) B 5 - 125 (0.3-8.5) C 10 - 200 (0.7-13.6) Flow Coefficient Cv Size Materials of Construction Component Body, Spring Chamber Spring Button, Adjustment Screw Lock Nut, Bottom Plug, Panel Nut, Diaphragm Nut, Turbulence Pin Diaphragm Plate Forged Brass, ASTM 377 Brass, ASTM B16 Bottom Plug O-ring Brass, ASTM A36 303 Stainless Steel, ASTM A582 Brass, ASTM B16 and EPDM / FKM EPDM / FKM Plated Music Wire, ASTM A228 Phosphorous Bronze, ASTM B103 EPDM / FKM Diaphragm Gasket Diaphragm Diaphragm Screw Red Fiber EPDM / FKM on Nylon Nylon 101 (Type 66) Adjustment Screw Valve and Stem Assembly Valve O-ring Adjustment Spring Valve Spring
