730E 732E

Brand：Pneumatic eccentric butterfly valve 型號(hào)：730E 732E

feature
(1) Low fluid resistance, ball valves have the lowest fluid resistance among all valve types, even for reduced diameter ball valves, their fluid resistance is quite small.
(2) Thrust bearings reduce the friction torque of the valve stem, allowing for long-term balanced and flexible operation of the valve stem.
(3) The valve seat has good sealing performance and is made of sealing rings made of materials such as polytetrafluoroethylene. The structure is easy to seal, and the sealing ability of the ball valve increases with the increase of medium pressure.
(4) The valve stem seal is reliable. As the valve stem only rotates without lifting, the packing seal of the valve stem is not easily damaged, and the sealing ability increases with the increase of medium pressure.
(5) Due to the good self-lubricating properties of materials such as polytetrafluoroethylene, the friction loss with the ball is small, and the service life of the ball valve is long.
(6) The bottom mounted valve stem and the protruding step at the head of the valve stem prevent the valve stem from spraying out. In the event of a fire causing damage to the valve stem seal, the protruding step can also form a metal contact with the valve body to ensure the valve stem seal.
