Solution to Cylinder Air Leakage Problem of Soft Sealed Gate Valve

December 22, 2023

To solve the cylinder leakage problem of soft-sealed gate valve, we must consider it according to the actual situation. For example, this valve is air-opened or air-closed. For the air-opened valve, we can first close the valve at both ends of the valve, and then Let the control open the valve, disconnect the connection piece at the connection first, and then cut off the gas source. At this time, the gas at the relief valve will be let go. Notice that the actuator will rotate at 90°C and finally change it. Afterwards, we must pay attention to moving the actuator back to its original position. Solution:

1. Replace the sealing ring of the actuator.

2. Replace the sealing ring at the cylinder.

3, to adjust the pressure of the valve to 3-5 kg, or to open the lower part of the solenoid valve vent action several times, and sometimes it is possible to replace the solenoid valve.

4. Replace the spring in the cylinder.
