                                                        300LB WCB Non-Rising Stem Knife Gate Valve with Bonnet

Bonnet Knife Gate Valves are a unidirectional valves designed for isolation application where Solid‐Liquid mixes, corrosive, abrasive, viscous liquid, abrasive slurries, pulp stock and dry materials are involved. The Bonnet is cast or fabricated depending on valve size and pressure rating of the valve. Sealing to atmosphere is achieved using a round gland sealing arrangement on top of the bonnet. This assures very tight sealing which is not normally feasible on standard knife gate valves with a large rectangular packing area. Bonnet valves are generally used for buried services where
backfill covers the valve and also suitable for application requiring a high level of gland tightness such as dangerous and toxic gases. The
bonnet also prevents internal corrosion from fluid handled. Flush ports also provided to clean the bonnet periodically.Purging can be made with air, steam, liquids, etc. depending on the fluid handled.
