Benefits & Features

  • Soft Seat option – provides repeatable leak-tight performance before and after each relief cycle. Allows for reduced maintenance costs, multiple cycles with tight shut-off, and high seating seating integrity (Models 330, 330S and 333S).
  • Lightweight aluminum construction. Resistant to environmental and internal corrosion.
  • Repetitively consistent opening pressure.
  • Smooth relief action.
  • Positive reseating with minimal pressure drop.
  • Model 230 (non-code) 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).
  • Seat tightness increases as inlet pressure approaches set (opening) pressure.
  • Each Kunkle valve is tested and inspected for pressure setting and leakage.
