Pneumatic valve diaphragm precautions

1. The opening and closing direction of the pneumatic valve should be closed clockwise.

2. Since the pneumatic valve in the pipe network is often manually opened and closed, the number of rotations for opening and closing should not be too much, that is, the large-diameter valve should also be within 200-600 rotations.

3, in order to facilitate a person's opening and closing operations, in the pipeline pressure conditions, the maximum opening and closing torque should be 240N-m.

4. The opening and closing operation end of the pneumatic valve shall be a square bracket, standardized in size and facing the ground so that people can directly operate from the ground. Wheeled valves are not suitable for underground pipe networks.

5. Pneumatic valve diaphragm should pay attention to the fullness of the contact place during use, and the working time should not be too long to avoid excessive damage to the device and cause loss to you. Because the working environment of the pneumatic valve diaphragm is high temperature, do not use it at high speed. Use in environments with excessively low temperatures to avoid unnecessary damage to the device.
