The types of exposed stem gate valves can be divided into wedge gate valves and parallel gate valves according to the sealing surface configuration. Wedge gate valves can be divided into: single gate type, double gate type and elastic gate type; parallel gate type gate valve It can be divided into single gate type and double gate type. 

Divided according to the thread position of the valve stem, it can be divided into two types: open stem gate valve and dark stem gate valve. When the exposed stem gate valve is closed, the sealing surface can be sealed only by the medium pressure, that is, the sealing surface of the gate is pressed against the valve seat on the other side by the medium pressure to ensure the sealing of the sealing surface, which is self-sealing. Most gate valves adopt forced sealing, that is, when the valve is closed, the gate must be forced against the seat by external force to ensure the sealing performance of the sealing surface.


The valve should be used for open ,close and regulating medium flow in pipeline of petroleum,chemical,food,

medicine,metallurgy,ship,can also be used in a variety of corrosive medium,the following feature.

  1. Excellent bidirectional sealing performance,minimized operation torque.

  2. Flow characteristics tend to be straight,good regulation performance.

  3. Choosing different materials, can be used in corrosive medium.

  4. Simple and compact structure,compact and light,easy to transport,install

    and disassemble.
