1. Adopts no diversion hole support type double ram structure, the ram adopts support type double ram structure, the middle part of the two RAMS is made of eight shape inclined plane, and the wedge block is arranged in the middle of the inclined plane. 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 upper end of the main gate is fixed to the valve stem, and there is a V-shaped bevel between the main gate and the contact surface of the slave gate, which greatly enhances the sealing effect

4. When the valve is fully opened, the flow resistance coefficient is very small, and the valve will eliminate the action of the valve disc and the dirt on the sealing surface every time the valve is opened and closed.

5. The packing is made of flexible graphite ring and graphite packing, reliable sealing, light and flexible operation.

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