Overview
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.
Advantage
Trunnion mounted ball valve is an economical and high-performance quarter-turn valve. The quarter-turn operation is fast and reliable which makes this valve applicable to quick on-off operation and tight seal. This ball valve is widely used in pulp paper refinery, mining, chemical fiber, sewage and water treatment, sugar refining industry.
Body:
Separate body design, various materials are available.
Ball:
The ball is trunnion mounted, which prevent seat damage and reduce seat ware dramatically comparing with floating ball valve.
The ball is precisely machined and mirror finished for bubble-tight shutoff and less operating torque.
Full bore design minimizes the flow resistance and achieve better valve performance.
Seat:
With seats on both sides,the trunnion ball valve can handle flow in either direction with 0 leakage.
Seat is spring preloaded, which ensures self
Application
The trunnion ball valve is a kind of double-block-and-bleed(DDB) valve, while the floating ball valve only seal the downstream side.The trunnion ball valve can block both upstream and downstream media. And when the pressure in the middle cavity is greater than the seat spring force, the seat will be pushed open to release the pressure inside the chamber to ensure safety.
