Z41H Series of steel gate valves

[Product Overview]
The gate valve refers to the valve that the closing part(gate) moves in the vertical direction along the axis of the channel. It is mainly used as a cutting medium on the channel, that is, it is fully open or fully closed. In general, the gate valve can not be used as an adjustment flow. It can be applied to low temperature and low pressure or to high temperature and high pressure, and can be used in various media according to different materials of the valve. However, gate valves are generally not used in pipelines that transport media such as mud.
[Product characteristics]
1. The fluid resistance is small, and the dense cover is scoured and eroded by the medium.
2. It is easier to open and close.
3. The flow of the medium is unrestricted, does not disturb the flow, and does not reduce the pressure.
4. Simple body, short structure length, good manufacturing process, wide range of application.
Type of gate valve: according to the dense cover configuration can be divided into wedge-type gate valve and line gate gate valve, wedge-type gate valve can be divided into: single gate type, double gate type and elastic gate type; Parallel gate type gate valve can be divided into single gate type and double gate type.
