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 used for cutting or connecting the medium in various pipelines of class150-class2500 and pn16-pn320. It can be suitable for various media such as water, steam, oil, liquefied gas, natural gas, coal gas, nitric acid, acetic acid, oxidizing media, urea and etc. It is widely used in such industries as chemical industry, petroleum, natural gas, metallurgy and etc. The driving modes of the trunnion ball valve include worm and worm gear driving, manual driving, pneumatic driving and electric driving. The trunnion ball valves generally adopt flange connection, and butt-welding connection is also adopted. The seat can be soft seal seat or metal hard seal seat.
