Trunnion mounted designs for forged steel trunnion mounted ball valve is available for over 2" size and are generally used for higher pressure. Three pieces body, blow-out proof stem, antistatic device, fire-safe designed and certified, double block and bleed, self relieving. Execution could be full bore or reduced bore, and materials can be carbon steel, stainless steel, special alloys resilient or metal seated These have the ball mounted on trunnions supported in body bearings above and below the ball. sealing is achieved by spring loaded piston type seats which shut off flow when line pressure acts on the upstream seat. This design provides automatic rilief of cavity overpressure.

Characteristics of api trunnion mounted ball valve 1. Design and manufacture of ptoduct according to american state standard ansi b16.34, american petroleum institute standard api608 api6d. 2. Liquid resistance smallest of all type of valve. 3. Open quickly, only turn on 90 degree may finilsh open and close. 4. Seat material use teflon or r-teflon, low friction, seal reliable open and close lightly. 5. Movement of ball on the middle of valve seat has wipe function so may suit medium of suspending granule. 6. Stem use back seal and hyperbatic structre which may prevent medium to striking stem on the condition of pressure. 7. According to the need of consumer, may design for anti-static electricity, fireproop and use a locker to prevent wrong operator. 8. Body of ball can be floated or fixed accordance with the of strength of opening and closing. Seat of fixed ball valve floatablerealize seal purpose depend on piston effect of medium pressure so to lighten the strength of open and close.
A ball valve is a form of quarter-turn valve which uses a hollow, perforated and pivoting ball to control flow through it. It is open when the ball's hole is in line with the flow and closed when it is pivoted 90-degrees by the valve handle.The handle lies flat in alignment with the flow when open, and is perpendicular to it when closed, making for easy visual confirmation of the valve's status. Ball valves are durable, performing well after many cycles, and reliable, closing securely even after long periods of disuse. These qualities make them an excellent choice for shutoff and control applications, where they are often preferred to gate and globe valves, but they lack their fine control in throttling applications.
