Wafer Butterfly Valve With Pneumatic Actuator DI

Precautions For Use

Before installation, the staff needs to check whether the diameter of the valve matches the pipeline, whether there are serious bumps and scratches on the valve during transportation, and tighten the bolts during installation to ensure that the entire valve is evenly stressed.

When connecting the gas source, it is necessary to slowly open the gas source valve to check for any jamming or unstable operation. If there is any foreign object blockage, it can be disassembled for inspection. The limit switch ensures that the output of the signal is consistent with the actual position of the valve. And when switching to manual mode, the staff should apply force at a constant speed.

Regularly inspect the sealing valve seat to see if there are any impurities or severe wear. But if the valve is not used for a long time, it is recommended to open the valve to a semi open state to prevent the valve plate and seat from sticking.

Product Advantages

The manual mechanism can operate stably through the rotation of the turbine, and can quickly switch to manual mode when there is a problem with the pneumatic system. The limit switch can provide real-time feedback on the opening and closing status of the valve.

All components of the pneumatic butterfly valve with limit switch and manual mechanism are of uniform specifications and standards. If the butterfly valve needs to be replaced, it can be easily operated, effectively reducing labor costs.
