Stop valve J41W

Shanghai valve valve Co. Ltd. Yang production, also called the door, is the most widely used as a valve, it is popular is because the process of opening and closing the sealing surface friction between the small, more durable, highly open small, easy manufacture, convenient maintenance, not only for low pressure, but also suitable for high pressure.

The closing principle of the stop valve is to rely on the valve bar pressure, so that the valve sealing surface and seat sealing surface close together, to prevent the circulation of media.

The one-way valve can only medium flow direction when installing. The structure length of the stop valve is larger than the gate valve, and the fluid resistance is large. The reliability of the sealing is not strong in the long run.

Stop valve has the following advantages:

1, simple structure, manufacturing and maintenance is more convenient.

2, small working time, short opening and closing time.

3, good sealing, friction between the sealing surface is small, long life.
