The opening and closing part of the gate valve is a gate. The movement direction of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate has two sealing surfaces. The two sealing surfaces of the most commonly used model gate valve form a wedge. The wedge angle varies with valve parameters, usually 50, and 2°52' when the medium temperature is not high. The gate of the wedge gate valve can be made into a whole, called a rigid gate; it can also be made into a gate that can produce a small amount of deformation to improve its manufacturability and compensate for the deviation of the sealing surface angle during the processing. The plate is called an elastic gate.


1. Exquisite selection of materials, in line with relevant standards, and high quality materials.

2. The valve fully meets the requirements of the standard, with reliable sealing, excellent performance and beautiful appearance.

3. The sealing pair is advanced and reasonable. The sealing surfaces of the gate and the valve seat are reliable, high hardness, wear resistance, high temperature resistance, and high temperature resistance. Good corrosion and scratch resistance and long life.

4. After quenching and tempering and surface nitriding treatment, the valve stem has good corrosion resistance, scratch resistance and wear resistance.

5. It adopts wedge-type elastic gate structure, middle and large diameters are equipped with thrust bearings, the friction is small, and it is equipped with impact manual operation, which can be opened and closed easily.

Design advantages:

1. The fluid resistance is small, and the sealing surface is less brushed and corroded by the medium.

2. It saves effort to open and close.

3. The flow direction of the medium is not restricted, does not disturb the flow, and does not reduce the pressure.

4. Simple shape, short structure length, good manufacturing technology and wide application range.

Field of Application:

Size Range: DN40 to DN500

Temperature: (-)29℃ to 425℃

Allowable Operating Pressure:JIS 10K

Gate valve is widely used in petrochemical plants, metallurgy, water treatment, thermal power plants and other oil and water vapor pipelines to connect or cut off the medium in the pipeline.

Technical Specification:

1.Face to face: JIS B2002

2.Flange ends: JIS B2212

Installation and maintenance:

1. Handwheels, handles and transmission mechanisms are not allowed to be used for lifting, and collisions are strictly prohibited.

2. The double gate valve should be installed vertically (that is, the valve stem is in the vertical position and the handwheel is on the top).

3. The gate valve with bypass valve should be opened before opening (to balance the pressure difference between inlet and outlet and reduce the opening force).

4. The gate valve with drive mechanism should be installed according to the product manual.

5. If the valve is frequently opened and closed, lubricate at least once a month.
