Product Description

Relief valves for air and gas services with models to ASME section VIII, gas ‘UV’, National Board certified and PED certified for non-hazardous gas

Features

  • Lightweight aluminum construction is resistant to environmental and internal corrosion.
  • Repetitively consistent opening pressure.
  • Smooth relief action.
  • Positive reseating with minimal pressure drop.
  • Soft seat option provides repeatable leak-tight performance; allows reduced maintenance costs, multiple cycles with tight shut-off and high seating integrity (Models 330, 330S and 333S).
  • Model 230 (non-code) is direct spring-loaded design with synthetic disc insert.
  • Model 330 series’ differential mechanism maintains a predetermined seat contact load.
  • 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 valve tested and inspected for pressure setting and leakage.
