The trunnion ball valve is a quarter-turn valve which uses a hollow, fixed ball to control flow.
The high quality metal & soft seated trunnion ball valves are designed for many applications in the oil and gas, petrochemical, power & general process industries.
Trunnion Mounted Ball Valve
The trunnion design employs a ball, with two trunnions, affixed to the ball at the top and bottom. The unit fits into a space in the valve body and cannot move along the flow axis.
Trunnion ball valves are suited to high pressure or larger size valves with lower operational torque and long durability.

The trunnion ball valve is generally used in these applications:
- Oil & Gas
- High-temperature services
- High-pressure services
- High-cycle and switching services
- Emergency shutdown valves
- High-integrity pressure protection system
