HIGH CAPACITY PRESSURE REGULATOR 1/4", 3/8” and 1/2" NPT Inlet 400 Psig (27.6 Bar) Description The Generant Series HC, High Capacity Regulators are ideally suited for industrial applications requiring a rugged high flow pressure regulator. The Series HC features Heavy Duty all metallic body and spring chambers and are easily rebuilt in the field. The Series HC is available in Relieving and Non-Relieving configurations ideally suited for both liquid and gas service. 3/8" and 1/2" Regulators are fully balanced to maintain constant delivery pressure regardless of inlet pressure fluctuations. 1/4" Regulators are currently available non-balanced only. Available Relieving or Non-Relieving 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) Temperature Range: -20 to 200 °F (-30 to 95 °C) Pressure Ranges Spring Outlet Pressure Range Code 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 Fail Open Materials of Construction Component Body Spring Chamber Spring Retainer HCHCR375/500 375/500 Forged Brass, ASTM 377 Forged Brass, ASTM Die Cast Zinc (Zamak) 377 N/A Die Cast Zinc (Zamak) Spring Button Diaphragm Screw Diaphragm Plate / Nut Adjustment Screw Adjustment Screw Lock Nut Chamber Insert Brass, ASTM B16 Nylon 6-6, Brass, ASTM ASTM AD589 B16 Valve O-ring Adjustment Spring Valve Spring Turbulence Pin Bottom Plug Bottom Plug O-ring Sieve Diaphragm Gasket Diaphragm Panel Nut 303 Stainless Steel, ASTM A582 Brass, ASTM B16 Plated Steel Valve Stem Valve Assembly Brass, ASTM B16 Brass, ASTM B16 and FKM, ASTM D1418 N/A Plated Music Wire, ASTM A228 302 Stainless Steel, ASTM A313 18-8 SS, ASTM A276 17-7 Stainless Steel, ASTM A564 Brass, ASTM B16 Brass, ASTM B16 Buna-N N/A N/A Buna-N and Nylon Brass, ASTM B16
