Before the valve is installed, it is necessary to check whether the surface and moving parts are damaged, and then install the valve on the pipeline according to the requirements. During daily use, the staff needs to maintain the moving parts exposed to the air, such as applying lubricating oil. When there is a problem with the valve, the staff first needs to close the pipeline, then check the inside of the valve to find out the problem, and then carry out corresponding repairs; sometimes the sealing surface needs to be polished, and sometimes the valve stem or gate needs to be replaced.
Customers can communicate with sales staff by phone, SMS, and email. Customers can describe the problems of the valve to sales staff or take pictures, and then sales staff will provide corresponding solutions. During the one-year warranty period, Gangye can dispatch work personnel to repair the valve or provide a brand-new valve for replacement.
