features
knife gate valve is one of the most preferred industrial valves. It is featured with minimum contact between moving parts of the valves. In this type of valve, a gate is practically held between layers of gland packing without touching the body parts during most of its travels.
the seating is accomplished with a non-sliding motion aided by jams located in the body. Avoiding sliding contact between gate and body permits this valve to handle abrasive particles present in the media much better than conventional designs.
This valve is named 'knife' because of the beveled bottom edge of the gate. It allows positive closure of the gate even when solid particles settles at the bottom of the body.
In abrasive media, deflection cones are used to avoid direct impingement of the media on the seat surface. Besides this, sometimes hard facing of seat part is also used, which involves stelliting of the seat or gate or complete intruding of body as well as gate.
Another feature is the purge connection which allows the flow of suitable fluids at pressures higher than line pressure in order to clean seating surfaces (body purges) and packing area (chest purges). This helps in minimizing abrasive wear and tear during opening and closure of valve. Knife gate valves are excellent hopper isolation valves with their ability to cut through flowing powders and close by dislodging any material in the seating area. Specially designed to tolerate differential thermal expansion of its parts without affecting its functions, this valve is an ideal choice for handling high temperature media
