Selectomite® 76 Series 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
- Conpressed natural gas dispensing
- Instrument air lines
- Sampling systems
- 2-way gauge readout of line pressure
- Down hole control systems on offshore drilling platforms
Features & Benefits
- Blowout-proof stem for added safety.
- Trunnion design assures leak-tight sealing at full 6000 psig [414 bar] differential pressure for high pressure applications.
- Handle points to port in use or to closed position, providing a visual clue and improved safety.
- Encapsulated dual Nylatron® seats and Viton® stem seal ensure a leak-tight seal. This combination provides greater valve reliability.
- Special High Tolerance NPT Thread
