Valves rise to be an important role in the industrial process. In order to make the valve function at its best, periodical examines and careful performances are quite necessary. You can have a look of what the things you can do in order to keep the valve at a best state as following.
When you buy a valve for future use, you should take care of it. Otherwise, the machine would work with potential malfunctioneven fail to work at first. In the first place, you had better to put the new valves in the indoor cool place. The place with heavy moisture, high temperature is without regards. The idea of putting them in mess and outside is forbidden. Specially, the surfaces of the valves need special attention. For example, we should cover ports of either side of the ball valves and store them in open position. It is similar situation with the gate valves, globe valves and check valves, but they should be stored in close position.
When you need to take them out from the storage, there are a lot of things which you had better to take note of. Before the installation, you should make sure that the valve is going to reach your requirements. Furthermore, it is important to avoid the damage caused by the delivery process.
It is quite crucial during the installation process. When you connected with the pipe, especially for the pipes with small and medium specifications, be seriously careful please. Negligence would cause great expense. Then, it is high time for a trial run. Be prepared to the things would happen. If some problems occur, it is urgent to solve before its normal operating.
When the valve is carried out into operating, we should perform it according to the instruction. Taking the ball valves, check valve and gate valves for example, the clack should be fully open of filly close. Otherwise, the sealing face would get worn by fluid. It is necessary to use hand wheels to open and close ball valves, check valves and gate valves and so on, not the leverage or other tools, because others would damage the mechanical parts. It is better to develop the habit of turning handwheel clockwise to close the valves and turn handwheel counterclockwise to open the valves. The idea of keeping clean should be remembered all the time. Regular maintenance is needed. Failure logging is appreciated.
