Pneumatic valve installation and maintenance

Pneumatic valve, pneumatic valve installation maintenance, should pay attention to the body to sign, in order to avoid flow direction error, affect the use. , in use process such as the discovery of gland leakage, tighten a press cover bolts can be solved. Crank arm to the lag structure, pneumatic actuators, used for manual device, fault when removing the air supply pipe directly with a manual wrench manual operation can be realized. , pneumatic valve before use under the premise of should confirm that the valve is fully open to break the wash pipe, in order to avoid has the sundries such as welding slag scratch sealing surface. , pneumatic valve can be installed in vertical lie within the range level °, never will flip pneumatic actuators downwards. , pneumatic valve is generally set by-pass pipe, at the time of repair or replacement of pneumatic valve and the by-pass pipe using the process as usual can be used for. , the locator or electromagnetic valve please refer to the manual for debugging. Pneumatic valve considerations, when installed, the disc to stop in the closed position. , open position should be according to the board to determine the Angle of rotation. And valve with a bypass valve, open the bypass valve should be taken before opening. , shall be installed according to the manufacturer's installation instructions and big weight of valve, should set up a solid foundation.
