1.Before installation of manual butterfly valve, do not throw it away at will, it should be placed in a cool, dry and ventilated environment, and should be well covered, to avoid the valve contaminated with dust and other sundries, affecting the use of late.
2.Before installing on the pipe, check the pipe first, the position of the pipe at both ends should be consistent, there should be no deviation, otherwise, if there is deviation in the pipe, install the manual butterfly valve, it will cause tension or rupture of the valve body.
3.In addition to pipeline calibration, there is a preparatory work prior to installation, which is to perform a sweep of the manual butterfly valve to be installed and its piping to ensure that the valve and piping interior are clean, otherwise the sealing effect of the valve will be affected.
4.Manual butterfly valves require frequent manual operation. So the installation position of manual butterfly valve is also very exquisite, the valve installation position must facilitate the operation of personnel and future maintenance, there is proof that the best position for manual valve installation is the operation floor 1.2 meters or so. For valves installed outdoors, cover the valve with some cover to prevent adverse weather effects.
5.Installation, the manual butterfly valve disc must be in the closed state, lest the disc and pipeline flange collision damage, affect the sealing performance.
6.After installation, to carry out debugging, if in the process of use, manual butterfly valve opening and closing fault, to find out the reason, to eliminate the fault, can not be knocked, pry or by brute force forcibly opened and closed.
The installation requirements of manual butterfly valves are actually very simple, we need to pay attention to the details of valve procurement. Pipeline safety and valve life are also critical.
