Knife gate valve

This is a flat valve with full bore, metal or resilient seat outside screw and suitable only for low pressures, DIN or ANSI.


1. The short structure, manufacturing materials and piping systems can greatly reduce the total weight
2. The resistance of the pipes can reduce the possibility of valve vibration
3. Great resistance to corrosion
4. Flexible PTFE packing, reliable closing, flexible and light
