Pneumatic Fixed Ball Valve is O-type pneumatic fixed ball valve with upper and lower stem fixed spool (shaft-supported) and movable seal seat design, work more stable.
Pneumatic Fixed Ball Valve has automatic compensation function and has large shearing force and self-cleaning function when there is no gap between two-way sealing valve seats.
It is especially suitable for the opening and closing of imperial fibers and suspensions with fine solid particles and viscous media.
Pneumatic Fixed Ball Valve can be widely used in the automation control system of paper, petrochemical, chemical, metallurgy, electric power, environmental protection, petroleum, light industry and other industrial sectors.
1: With fixed ball design, the relative motion parts are made of self-lubricating material with very small friction coefficient, so the operating torque is small, and the long-term sealing of the sealing grease makes the operation more flexible.
2: The valve adopts high platform structure and ISO5211 connection standard, which can make the installed actuator more professional.
3: The ball valve adopts full diameter or reduced diameter design, and the flow resistance is small.
4: Metal hard seal O-type fixed ball valve adopts two-way metal movable sealing structure, with automatic compensation and self-cleaning function, excellent sealing performance.
5: The ball valve has an automatic pressure relief function.
6: Each ball valve has two movable sealing seats, which do not need to consider the flow direction of the medium during installation.
7: With fire and anti-static structure.
