Compared to floating ball valves, trunnion mounted ball valves feature an additional support for the ball from the bottom. This support is called trunnion. The trunnion absorbs any pressure from the flow and keeps the ball constantly in the same position. The sealing is provided by spring-loaded seats. This design reduces the stress on the ball and seats of the valve and makes the sealing performance more stable and consistent, independently from the flow pressure. Trunnion mounted ball valves are ideal in high-pressure services, while allowing for low operating torque requirements.
Fully welded, full port, straight ball, trunnion mounted ball valves, designed specifically for natural gas distribution systems.
Manufactured from high grade carbon steel material, they can be used in below ground or above ground applications.
Features:
- 304 stainless steel balls and stem standard
- Standard horizonal gear operator or optional vertical gear operator
- Positive stops
- Seats of 25% carbonized PTFE (Teflon) (G-453) rated to -20F
- Zinc coated stem bearings
- Serial numbered for full traceability
- Trunnion mounted, 100% full port
- API 6D tested
