The Wey Knife Gate Valve Model VS is truly a high performance knife gate valve design. This valve provides zero leakage bi-directional shut-off, has mechanically retained seals, has a compact non-rising stem design, and can be repacked in service under full pressure. 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 repackable while in service under full pressure. The valve is tested and rated for zero leakage (liquid or gas) downstream and to atmosphere.
