1. Before installing the flange butterfly valve, check that there are no missing parts of the pneumatic butterfly valve, the model is correct, check the valve body for no debris, and there is no blockage in the solenoid valve and silencer.
2. Put both the valve and the cylinder in the closed state.
3. Crash the cylinder onto the valve. (The installation direction can be parallel or perpendicular to the valve body.) If the screw hole is aligned, there will be no deviation. If there is a slight deviation, the cylinder block can be rotated a little. , then tighten the screws.
4. After the installation is completed, the pneumatic butterfly valve is debugged (normally, the air supply pressure is 0.4~0.6MPa), and the solenoid valve must be manually opened and closed during commissioning operation (manual operation can be effective after the solenoid valve coil is de-energized) Observe the opening and closing of the pneumatic butterfly valve. If during the commissioning operation, it is found that the valve is a little difficult at the beginning of the opening and closing process, then it is normal, then the cylinder stroke should be adjusted down (the stroke adjustment screw at both ends of the cylinder should be adjusted at the same time, and the valve should be moved to the open position during adjustment. Then turn off the air supply and adjust it until the valve opens and closes smoothly and closes without leakage. It should also be noted that the adjustable silencer can adjust the opening and closing speed of the valve, but it can not be adjusted too small, otherwise it may cause the valve to not operate.
5. The hair should be kept dry before installation, not open storage.
6. Check the pipeline before installing the butterfly valve to ensure that there are no foreign objects such as welding slag in the pipeline.
