These are some of the methods used. In order to achieve a better safety state, there are also many things to pay attention to during the installation. It is necessary to ensure that all parts are in the normal temperature state during the installation, because the high and low temperature will cause the parts to expand in a certain way, which will affect the fixation of the internal parts of the pneumatic ball valve, Of course, when the parts begin to cool, it will be found that the connecting part is still loose, which will cause a great potential safety hazard, which needs attention.

For commissioning of pneumatic butterfly valve, first check whether the valve accessories are complete, solenoid valve and silencer, etc. If there is any incompleteness, commissioning is not allowed. The normal air pressure of the feeder is 0.6MPA ± 0.05MPA. Before operation, ensure that there is no debris stuck in the valve plate inside the valve body. During the first commissioning operation, manually operate the solenoid valve manual button (when the solenoid valve coil is de energized during manual operation, manual operation is useful; During the electric control operation, the manual operation is useful only when the manual knob is set to position 0 and the power is lost; Position 0 is to close the valve, position 1 is to open the valve, that is, power on the valve. If power off the valve is required to close the valve, power off the open position is to close the valve and rotate the solenoid valve coil 180 degrees), and investigate the valve operation. If in the process of commissioning and operation, it is found that the valve is very slow in the initial position of opening the valve, but it only needs to act quickly and then act quickly. In the process of commissioning, it is found that the valve is very slow in the initial position of opening the valve, but it only needs to act quickly. This situation is that the valve is closed too tightly, Just reduce the stroke of the cylinder a little (adjust the stroke adjustment screws at both ends of the cylinder a little inward together, and turn the valve to the open position when adjusting, and then turn off the air source before adjusting), until the valve is open easily and closed in place without leakage. If the silencer is adjustable, the opening and closing speed of the valve can be adjusted. If the silencer is adjusted too small, the valve may not act.
