Precautions for installing and using butterfly valves

Butterfly valves are mainly used for the adjustment and switch control of various types of pipelines. They can cut off and throttle in pipelines. In addition, butterfly valves have the advantages of no mechanical wear and zero leakage. However, butterfly valves need to know some precautions for installation and use to ensure the use of the equipment.

1. Pay attention to the installation environment

According to the analysis of TWS Valve, in order to prevent condensed water from entering the butterfly valve actuator, it is necessary to install a heating resistor when the ambient temperature changes greatly or the humidity is high. In addition, the butterfly valve manufacturer believes that during the installation process of the butterfly valve, the flow direction of the medium should be consistent with the direction of the valve body calibration arrow, and when the diameter of the butterfly valve is inconsistent with the diameter of the pipeline, tapered fittings should be used. Moreover, TWS Valve suggests that the installation site of the butterfly valve should leave enough space for subsequent debugging and maintenance.

 

2. Avoid additional pressure

TWS Valve suggest that during the installation of butterfly valves, additional pressure should be avoided from the valve. Butterfly valves should be installed with support frames where the pipeline is long, and corresponding shock-absorbing measures should be taken in places with severe vibration. In addition, the butterfly valve should pay attention to cleaning the pipeline and removing dirt before installation. When the butterfly valve is installed in the open air, a protective cover should be installed to prevent it from being exposed to the sun and getting wet.

 

3. Pay attention to the adjustment of equipment

TWS Valve mentioned that the limit of the transmission device of the butterfly valve has been adjusted before leaving the factory, so the operator should not disassemble the transmission device at will. If the butterfly valve transmission device must be disassembled during use, it needs to be restored. Finally, the limit must be readjusted. If the adjustment is not good, the leakage and life of the butterfly valve will be affected.
