Tips for installing a pneumatic butterfly valve

Before installation, check whether all parts of the pneumatic butterfly valve are missing. Check for debris in the valve body, blockage in the solenoid valve and muffler.
Put the valve and cylinder in the closed state.
Install the cylinder on the valve (the installation direction can be parallel or perpendicular to the valve body), and then check whether the screw holes are aligned. There will not be much deviation. If there is a little deviation, just turn the cylinder body a little. , and then tighten the screws.
After the installation is completed, debug the pneumatic butterfly valve.
It should be kept dry before installation and cannot be stored in the open air.
Before installing the butterfly valve, check the pipeline to ensure that there is no foreign matter such as welding slag in the pipeline
Open the butterfly valve completely, and use a wrench to tighten the bolts in diagonal order without washer. Do not over-tighten the bolts to prevent serious deformation of the valve ring and excessive opening and closing torque.
