When using the pneumatic switch ball valve, the first thing to do is to open the valve. After the valve is opened successfully, you can wait for the actuator to connect with the main power supply. Because the ball valve mainly uses compressed air to generate continuous power to drive the work of the valve, so it is necessary to allow air to enter. When you see that the piston inside begins to move, It can be proved that the ball valve is successfully opened.

In order to reduce the operating torque of the pneumatic ball valve and increase the reliability of the seal, the oil sealed ball valve is presented, which not only injects special lubricating oil between the sealing surfaces to form an oil film, which not only enhances the sealing performance, but also reduces the operating torque, and is more suitable for high-pressure large caliber ball valves.
