Models 230, 330, 330S, 333S - Relief Valves

ASME Section VIII, Gas, 'UV' National Board Certified

Pressure Range: 300 psig to 6500 psig

Temperature Range:
-20 °F(-28.89°C) to -185 °F(-301°C)
Features and Benefits:
  • Lightweight aluminum construction. Resistant to environmental and internal corrosion.
  • Aluminum parts are anodized for corrosion resistance.
  • Model 230 is direct spring-loaded design with synthetic disc insert.
  • Model 330 series incorporates a differential mechanism which maintains a predetermined seat-contact load.
  • The full spring load is never imparted to synthetic disc insert (models 330, 330S, and 333S only).
  • Seat tightness increases to a maximum as inlet pressure approaches the opening pressure.
Applications:
  • Multi-stage high pressure compressors, intercoolers and aftercoolers.
  • High pressure receivers and storage bottles.
  • Thermal expansion relief.
