In the opening, first lift the wedge block, so that the left and right gate from the seat before lifting; When closing, the left and right ram are moved in place first and then opened to seal with the seat, which can reduce the wear of the seal pair.

2. When the valve is open and closed, the gate plate and the seat are kept in a sealed match state, and the medium in the valve body can be discharged. The sealing pair has little wear and good sealing performance.

3. The gate plate of the valve with a diversion hole, whether fully opened or fully closed, is always consistent with the sealing surface, and the sealing surface is protected from direct erosion by the medium, thereby extending the service life.

4. When fully opened, the channel is smooth and straight, the flow resistance coefficient is minimal, there is no pressure loss, and the pipeline can be cleaned with hairball.

5. The valve is suitable for various media, including water, oil, gas, etc., widely used in petroleum, chemical industry, metallurgy, electric power and other industries.
