Tips: How to maintain the pneumatic butterfly valve?
- During use, the pneumatic butterfly valve should be kept clean frequently, and the transmission thread must be lubricated regularly. When a fault is found, it should be stopped immediately, and the cause should be identified to clear the fault.
- The bolts of the packing gland should be tightened evenly, and should not be pressed into a crooked state, so as to avoid bumping and hindering the movement of the valve stem or causing leakage.
- When the pneumatic butterfly valve is used, it is only fully open or fully closed, and it is not allowed to adjust the flow, so as to avoid erosion of the sealing surface and accelerated wear. There are inverted sealing devices in the gate valve and the upper threaded globe valve. The handwheel is turned to the uppermost position and tightened to prevent the medium from leaking from the packing.
- Use the handwheel when opening and closing the pneumatic butterfly valve. Do not use levers or other tools to avoid damage to the valve parts. Turn the handwheel clockwise to close, and vice versa to open.
- Butterfly valves stored for a long time should be checked regularly. The exposed processing surface should be kept clean and the dirt should be removed. During storage, both ends of the ball valve should be blocked and open, and both ends of the channel should be blocked and closed for pneumatic butterfly valves. Store neatly in a ventilated and dry place indoors, and it is strictly forbidden to stack or store in the open air.
