1. One-piece knife gate valve with bidirectional sealing, zero leakage, withstand high differential pressure and full bore, can reach the maximum flow rate of the valve.

2. No groove valve seat design, to prevent media accumulation on the sealing surface, to avoid leakage on the sealing surface caused by media accumulation or gate jamming phenomenon.

3. Precision casting integral structure valve body

4. Elastic seat U-shaped design, embedded in the valve body and the gate plate coincides with each other, the gate up and down movement, friction is small, greatly extending the service life of the valve seat, and to achieve bi-directional sealing.

5. Rubber O-ring is embedded in the flange groove, the valve is easy to connect with the pipeline installation, reliable sealing.

6. The products are widely used in the fields of urban sewage treatment, paper making, mine slagging, etc.
