When the valve is closed, the gate compress the seal into the bottom of body groove, then the gate is sealed, bidirectional seal is realized. When the valve is opened, the gate leaves the seal, the seal bounces to the same height as the groove so that the residue can’t accumulate in the groove of the body.
YFL Bidirectional seal knife gate valves technical features:
1. Bidirectional seal realized by integral U shape seal
2. One-piece body design
3. Full port design
4. Reduce residue accumulation in the valve cavity
