Gate Valve- The Different Types

by Vatacvalves Xu Vatac Vango Valves (Wenzhou) Corp
A partially open Gate valve manufacturers can cause vibrations and permanent damage to pipes. The seating part of the valves can also be damaged by the fluid friction if the valves are partially opened. In these valves, the design is specifically aimed at completely blocking the flow or completely allowing the flow of water.

The rising stem and the non rising stem gate valve are the two different types of valves commonly used in most of the places today. The rising stem valve is identified by a threaded shaft which is rotated by a handle fixed in the centre. The stem or the shaft rises when the handle is rotated. It rises when the valve is opened and descends when the valve is closed. So it is easy to identify the position of the valve by length of shaft above.

The other variety of it includes the non rising stem valve which is used in places where there is space constraint. It is mostly used in underground pipes. Rotating the handles to the left opens the valves fully whereas rotating it to the right closes the valves completely. The stem of the shut off valve does not rise while opening and closing it.
