Pressure vs Temperature

Operation (2-way)

  1. Differential pressure is limited to 150 psig (10.3 bar) maximum if reverse flow occurs
  2. Reverse flow throttling may damage O-ring
  3. The graphs are based on FKM O-ring

Downstream Vents (2-Way)

Plug and valve body allow pressure to be released to atmosphere when closed. Maximum Working Pressure: 150 psig (10.3 bar)


The 3-way plug valve is in working state when the handle is in limit positions. There will be a short moment of interconnection for the three ports when rotating the handle.
