Sanitary Butterfly Valve installation requirements

1. Before installation, check that all parts of the pneumatic butterfly valve are intact and the model is correct. Check that there is no debris in the valve body. Solenoid valve

2. Put the valve and cylinder in the closed state.

3. Bump the cylinder onto the valve (the installation direction can be parallel or vertical to the valve body), and then see if the screw hole is aligned. There will not be too much deviation. If there is a slight deviation, just turn the cylinder body a little, and then tighten the screw.

4. After installation, debug the pneumatic butterfly valve (the air supply pressure is 0.4~0.6MPa under normal circumstances). During debugging and operation, the solenoid valve must be manually opened and closed (manual operation is effective only after the solenoid valve coil is de-energized), and observe the opening and closing of the pneumatic butterfly valve. If it is found that the valve is a little difficult at the beginning of the opening and closing process during the debugging and operation, and then it is normal, it is necessary to reduce the stroke of the cylinder (adjust the stroke adjustment screws at both ends of the cylinder a little at the same time, and the valve needs to be operated to the open position during adjustment, and then the air source is turned off and adjusted again), until the valve opens and closes smoothly and closes without leakage.
5. The butterfly valve should be kept dry before installation and should not be stored outdoors.
6. Before installing the butterfly valve, check the pipeline to ensure that there is no foreign matter such as welding slag in the pipeline.
7. The manual opening and closing resistance of the butterfly valve body is moderate, and the torque of the butterfly valve matches the torque of the selected actuator.
8. The flange specifications for butterfly valve connection are correct, and the pipeline clamp flange is consistent with the butterfly valve flange. It is recommended to use butterfly valve flanges and not flat welding flanges.
9. Confirm that the flange welding is correct. After the butterfly valve is installed, the flange must not be welded again to avoid scalding the rubber parts.
10. The installed pipeline flange must be aligned and aligned with the butterfly valve placed in it.
11. Install all flange bolts and tighten them by hand. Confirm that the butterfly valve and the flange are already aligned, and then carefully open and close the butterfly valve to ensure flexible opening and closing.
12. Open the valve *, tighten the bolts with a wrench in diagonal order, without gaskets, and do not tighten the bolts too much to prevent serious deformation of the valve ring and excessive opening and closing torque.
