Trunnion ball valve is a quarter turn valve intended for shut off service, while it
can also be used for throttle service in certain circumstances. Remote control
can be realized when pneumatic actuation and electric actuation are applied.
Manual operation is also available with hand lever and gearbox fitted. Spring
loaded seat and bidirectional seal design with seamless rotation of ball provide
a strong shear and good self-cleaning. It is especially suitable for the control
of fiber, suspension containing tiny solids and viscous fluid. Therefore, it is
widely used in process systems in indutries such as pulp and paper,
petrochemistry, petroleum, chemical fiber, power, metallurgy, pharmacy,
environmental protection, etc.
Superior sealing performance is available with both metal seat and PTFE seat
with spring loaded to serve as self-compensation and self-cleaning.
Bidirectional seal design assures reliable tightness at both directions.
Upper and lower shafts are fixed by bearings with good stability. Bearings are
in composite material, loaded surfaces of which are sintered with superior
abrasion resistant and self-lubricating function, which prevents valve seizing
up during service life.
Trunnion ball valve has the lowest flow resistance among all valve types. It is
the same way with the reduced bore one.
Full stroke is completed by a 90 degree rotation with swift open and close.
Therefore, it is sutable for automatic control and remote control.
Only rotation is happening to shaft during the full stroke, giving long service
life of packing. V-ring packing is adopted with pressure tightness to achieve
reliable shaft tightness.
