Pneumatic O-type cut-off explosion-proof ball valve Q641F-16P DN80

The pneumatic O-type cut-off explosion-proof ball valve Q641F-16P DN80 is composed of AT (GT) series pneumatic actuators and floating ball valves, suitable for regulating and cut-off applications. Explosion proof pneumatic ball valves have excellent sealing performance, high flow capacity, simple structure, long service life, and are easy to maintain. The equipped actuator has the characteristics of simple structure, compactness, high performance, and large output torque

Explosion proof pneumatic ball valve with explosion-proof strokelimit switchExplosion proofsolenoid valveThe pressure reducing valve and 0.4-0.7MPa gas source can achieve switch operation, and send two pairs of passive contact signals to indicate the switch of the valve. There are two types of actuators: single acting and double acting. The advantage of single acting type is that once the power source fails, the explosion-proof pneumatic ball valve will automatically be in the open or closed position according to the requirements of the control system. Explosion proof pneumatic ball valves are widely used in industrial fields such as chemical, petroleum, textile, power, food and pharmaceutical, refrigeration, aviation, aerospace, papermaking, etc. They are not only capable of controlling gas, liquid, and vapor media, but also suitable for controlling wastewater and substances containing fibers.

(1) Low fluid resistance, ball valve is one of the types of valves with low fluid resistance, even for reduced diameter ball valves, its 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.
