3-way Trunnion Valves
Developed for high pressure, side-loading applications, the 316 stainless steel trunnion is supported and held securely in position by two composite bearings. Encapsulated Nylatron seats provide a positive seal, resulting in leak-tight sealing between all ports to 6000 psig differential, reducing operating torque and increasing cycle life. The handle points to the side port in use; when perpendicular to the side ports, it indicates the shutoff position.

Typical Applications
  • Compressed natural gas dispensing
  • Instrument air lines
  • Sampling systems
  • 2-way gauge readout of line pressure
  • Down hole control systems on off shore drilling platforms
