Pump valve fittings Pneumatic butterfly valves need to be kept clean during use, and should be regularly lubricated for the transmission threads. When a fault is found, stop using it immediately and find out the cause to clear the fault. At the same time, the bolts of the packing gland should be evenly tightened, and should not be pressed into a smashing state, so as to avoid the movement of the valve stem or the leakage.
When installing, the pump valve fitting pneumatic butterfly valve can be directly installed on the pipeline. It can usually be installed at any position of the pipeline, but it needs to be easily operated. Note that the flow direction of the shut-off valve should be upward from the longitudinal valve flap, and the lift check valve can only be installed horizontally. When the pneumatic butterfly valve is used, it is only fully open or fully closed, and it is not allowed to adjust the flow to avoid the erosion of the sealing surface and accelerate the wear.
It should be noted that before the pump valve fitting pneumatic butterfly valve is installed, it is necessary to carefully check the pressure of the valve mark, whether the diameter meets the requirements for use, eliminate the defects caused by the transportation process, and eliminate the dirt of the valve member.http://www.pump-casting.com/
