The Guanli GKJ serie is truly a high performance Knife Gate Valve design. This valve provides ZERO leakage bi-directional shutoff,
has mechanically retained seals, has a compact rising stem and non-rising stem design. The chest and seating areas of the valve are self cleaning.
The reduced chest area, minimal gate arc, and contoured flushing corners in the body prevent jamming by eliminating material build-up in the chest,body and seating area.
The gate seals against a combination metal and resilient seat and is guided for the full stroke length of the valve.
The top "transverse seal is re-packable while in service under full pressure.
The valve is tested and rated for ZERO leakage (liquid or gas) downstream and to atmosphere.
