The trunnion ball valve is a form of quarter-turn valve which uses a hollow, perforated and fixed/supported ball to control flow through it.
A trunnion mounted valve means that the ball is constrained by bearings and is only allowed to rotate, the majority of the hydraulic load to be supported by the System constraints, resulting in low bearing pressure and no shaft fatigue. The line pressure drives the upstream seat against the stationary ball so that the line pressure forces the upstream seat onto the ball to cause it to seal.
The mechanical anchoring of the ball absorbs the thrust from the line pressure, preventing excess friction between the ball and seats, so even at full rated working pressure operating torque remains low. This is particularly advantageous when the ball valve is actuated because it reduces the size of the actuator and hence the overall costs of the valve actuation package.
Trunnion ball design is the lower operating torque, ease of operation, minimized seat wear (Stem/ball isolation prevents side loading and wear of downstream seats improving performance and service life)/superior sealing performance at both high and low pressure (a separate spring mechanism and upstream line pressure is used as the sealing against the stationary ball for low pressure and high pressure m applications).
The trunnion is available for all sizes and for all pressure classes but they are not suitable for throttling purposes.
Ball valves can be used in a variety of applications and marketssuch as transmission and storage, gas processing, industrial, and many more. that ball valves provide reliable leak protection which is especially beneficial in gas applications. Ball valves have low pressure drop and can open and close quickly.
A variety of construction materials, trim options and designs make these valves extremely versatile. Ball valves, such as RING-O subsea ball valves, are commonly utilized in subsea applications on manifolds that require long service life at high pressures. Ball valve also are used in cryogenic applications where compressed gas must be kept at a stable temperature in order to be moved efficiently.
