Ball Valve is a kind of quarter-turn valve which utilizes a hollow, perforated and pivoting ball (known as a "ball") to manage flow through it. It's open once the ball's hole is using the flow and closed when the ball valve’s pivoted 90-levels through the valve handle. The handle lies flat in alignment using the flow when open, and it is vertical with respect into it when closed, creating easy visual confirmation from the valve's status.


3-PC Body Trunnion Ball Valve
A trunnion ball valve has additional mechanical anchoring of the ball at the top and the bottom, suitable for larger and higher pressure valves.
The QDV trunnion mounted ball valves are suitable to stand the harsh service conditions often presented in the hydrocarbon industry, gas storage and transportation field. In general, they are recommended for tight shut-off in high pressure and double block and bleed applications
QDV valves 3-piece design body structure is available in forges steel. Valve body may be connected by bolts or welding.



Qiangda trunnion mounted ball valves feature: a full line product offering with valves ranging in 2"-42", ANSI classes 150LB - 2500LB, forged steel bolted or all welded body, close coupled trunnion block design for low operating torques, secondary seat sealant feature.Kojo API-6D valves are offered with self relieving seats or optional double piston sealing. Special seat compounds are also available. Each valve meets, API-6D, API 6FA and Nace requirements. Options include stem extensions, actuators, pipe pups and specialized coatings.
