Q41WC series takes the service life of vulnerable parts as the key point, selects materials with corrosion resistance, high hardness, high fatigue strength and good stability, and takes appropriate heat treatment, surface strengthening and other steps to effectively improve the service life of valve vulnerable parts. For the control mechanism, attention should be paid to such important parts as signal input/output, communication and drive. Through rigorous selection, a tight and stable system can be formed, effectively resisting the impact of severe working conditions such as deep cold and extreme heat on pipeline control. It has successfully applied a number of natural gas valves, and successfully applied natural gas series valves in the construction of the latest PetroChina Russia oil and gas pipeline and base station.

How does the pneumatic ball valve work? The ball of the pneumatic ball valve is transformed from the plug valve. Its ball center rotates by 90 °. The ball rotates around the center line of the valve body to open. There is a circular through hole or channel through its axis. When the ball center rotates to 90 °, the valve is tightly closed. When the actuator works, the valve can be tightly closed with only a small rotating torque, so that the principle of quick cut-off can be achieved. The pneumatic ball valve is mainly used in the flow pipeline for quick cutting off, distributing and changing the medium. The pneumatic ball valve can be opened and closed quickly and is suitable for large and small calibers. V-shaped ball can accurately adjust the medium flow.
