【Product Usage】

API American standard gate valve series products have the characteristics of small fluid resistance, small impact erosion on the sealing surface, no change of medium flow direction, no turbulence, small pressure drop, etc., applicable to a wide range of pressure and temperature, and are a common cut-off valve. It is suitable for connecting or cutting off the medium in the pipeline of petroleum, chemical, thermal power plants and other oil and steam pipelines (not used as a throttle valve).

【Basic Model】

The common basic models of API American standard gate valves are: Z40H, Z40Y, Z540H, Z540Y, Z940H, Z940Y and so on.


1. Compact structure, beautiful appearance, full-diameter flow channel, and small flow resistance coefficient.

2. The sealing surface is made of alloy steel or hard alloy, and the sealing pair materials are matched reasonably, and the service life is long.

3. The structure of the gate is: elastic wedge-shaped single gate or rigid wedge-shaped single gate. The surface of the valve stem is treated with nitriding, which has good corrosion resistance and friction resistance. The packing is made of flexible graphite, with reliable sealing, flexible operation and small opening and closing torque.

4. Various piping flange standards and flange sealing surface types can be selected, and various drive modes such as manual, worm gear, electric, pneumatic, and hydraulic can also be selected to meet different needs of users.
