Q641F stainless steel pneumatic ball valve

Overview of Q641F stainless steel pneumatic ball valve:

Stainless steel pneumatic ball valve is mainly used to cut off or connect the medium in the pipeline. It can also be used for fluid adjustment and control. Compared with other valves, it has the following advantages. (1) The fluid resistance is small, and the ball valve is the smallest fluid resistance among all valves. Even the reduced diameter ball valve, its fluid resistance is quite small. (2) The thrust bearing reduces the friction moment of the valve stem, which can make the valve stem operate smoothly and flexibly for a long time. (3) The valve seat has good sealing performance. The sealing ring made of PTFE and other elastic materials is easy to seal, and the valve sealing capacity of the ball valve increases with the increase of the medium pressure. (4) The valve stem is reliable in sealing. Since the valve stem only rotates and does not move up and down, the packing seal of the valve stem is not easy to be damaged, and the sealing capacity increases as the pressure of the medium increases. (5) Because materials such as polytetrafluoroethylene have good self-lubricating properties, the friction loss with the ball is small, so the service life of the ball valve is long. (6) The bottom-mounted valve stem and the convex step of the valve stem head prevent the valve stem from spraying out. If the valve stem seal is damaged due to fire, the convex step and the valve body can also form metal contact to ensure the valve stem seal. (7) Anti-static function: a spring is set between the sphere, the valve stem and the valve body, which can lead out the static electricity generated during the switching process.

Executive agency introduction:

Adopt a new series of GT pneumatic actuators, double-acting and single-acting (spring reset), rack and pinion transmission, safe and reliable; large-diameter valves adopt series AW-type pneumatic actuators with fork-pull transmission, reasonable structure and output torque Large, there are double-acting and single-acting.

1. Geared double pistons, large output torque and small volume.

2. The cylinder is made of aluminum gold material, which is light in weight and beautiful in appearance.

3. Manual operating mechanism can be installed on the top and bottom.

4. The rack-and-pinion connection can adjust the opening angle and rated flow.

5. The actuator can be equipped with electrical signal feedback instructions and various accessories to realize automatic operation.

6. IS05211 standard connection provides convenience for product installation and replacement.

7. The joint screws adjusted at both ends can make the standard product have an adjustable range of ±4° between 0° and 90°. Ensure the synchronization accuracy with the valve.
