Q641Q641 Pneumatic flange ball valve, Pneumatic flange ball valve, flange ball valve, ball valve

【 Valve characteristics 】

1, the flow resistance is small, the full-diameter ball valve is opened, the ball channel, the valve body channel and the connecting pipe diameter are equal and form a diameter, the medium can flow almost without loss;

2, pneumatic ball valve rotation 90° can be fully closed and fully opened, open and close quickly. Compared with gate valves and globe valves of the same specifications, ball valves are small in size, light in weight, and easy to install pipelines;

3, advanced valve seat: The valve seat designed with many years of ball valve manufacturing experience, to ensure that the valve seal, low friction coefficient, small operating torque, avariety of valve seat materials, wide range of adaptation;

4, switch correct handle: the use of flat head valve stem, and the connection of the handle will not be misplaced, so as to ensure that the switch state indicated by the handle is consistent with the valve;

5, locking device: in order to prevent the valve switch misoperation, there is a locking hole in the valve fully open and fully closed position to ensure that the valve is in the correct position;

6, the valve stem flight-proof structure: the valve stem is mounted under the pressure to prevent flying out, and can form metal contact with the valve body after the fire to ensure that the valve stem seal;

7, pneumatic ball valve is a ball with a round through hole as the opening and closing parts, driven by the valve stem the ball around the center of the valve stem for 0~90 degrees to complete the opening and closing function; It has the characteristics of compact structure and quick switching, turning 90 degrees, you can close the valve and cut off the pipeline medium; The valve stem is bottom-mounted, which prevents the accident of the valve stem threading and ensures the safety of use.

8, change the valve body, ball, seal material can be applied to a variety of working conditions, ball valve body can be integral, can also be combined.

【 Implementation standard 】

【 Valve use 】

Q641 pneumatic ball valve series products itself compact structure, reliable sealing, easy maintenance, sealing surface and spherical surface are often in a closed state, not easy to be eroded by the medium, easy to operate and maintain, suitable for water, solvent, acid and natural gas and other general working media, but also suitable for poor working conditions of the medium, such as oxygen, hydrogen peroxide, methane and ethylene, etc. It is widely used in various industries.
