Product catalog summary
Description
The Generant Series HC High Capacity Pressure Regulators are designed for industrial applications requiring robust, high-flow regulation. They feature a durable all-metallic body and spring chambers, suitable for both liquid and gas services, and are available in relieving and non-relieving configurations.
Features
  • 3/8" and 1/2" regulators are fully balanced to maintain constant delivery pressure despite inlet pressure changes. 1/4" regulators are non-balanced.
  • Available in relieving or non-relieving configurations.
  • Optimized spring performance and patented Venturi tube for high flow rates with low droop.
  • Easily cleanable by removing the 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 and Flow Coefficient (Cv)
  • Spring Code A: 0 - 50 PSI (0-3.4 bar), 1/4" NPT, Cv 1.6
  • Spring Code B: 5 - 125 PSI (0.3-8.5 bar), 3/8" NPT, Cv 2.4
  • Spring Code C: 10 - 200 PSI (0.7-13.6 bar), 1/2" NPT, Cv 2.9
Materials of Construction
  • Body: Forged Brass, ASTM 377
  • Spring Chamber: Forged Brass, ASTM 377, Die Cast Zinc (Zamak)
  • Various components made from Brass, Stainless Steel, Nylon, and Buna-N.
Flow Curve
Initial set pressures at 1 SCFM flow are 50 PSIG for A, 85 PSIG for B, and 150 PSIG for C. The dotted line on the flow curve represents a 10% decrease in outlet pressure from the setpoint (droop).
Ordering Information
  • Series: 4HC for Non-Relieving, 4HCR for Relieving
  • Port Size: 250 for 1/4", 375 for 3/8", 500 for 1/2"
  • Spring Range: A (0-50 Psig), B (5-125 Psig), C (10-200 Psig)
  • Options: M for Plastic Knob, P for Panel Mount
Repair Kits
  • Available for different models and sizes, including components like FKM Valve Assembly, Diaphragm Assembly, and O-Rings.
Installation Note
All regulators come with two 1/4" NPT pipe plugs supplied finger tight. Final installation is the responsibility of the end user. Proper component selection considering system design, material compatibility, and pressure ratings is crucial for safe performance.
