Sand Casting Heavy Duty Slurry Knife Gate Valve




The company holds expertise in manufacturing, exporting and supplying high grade Sand Casting Heavy Duty Slurry Knife Gate Valve. The Sand Casting Heavy Duty Slurry Knife Gate Valve, offered by us, facilitates flexible pressure assisted two-piece rubber sleeve system which allows valve to cycle in heavy slurries without sticking. The sleeves of our Sand Casting Heavy Duty Slurry Knife Gate Valve can be easily replaced without disassembling the valve. In addition to this, the bi-directional full port flow reduces pressure drop and turbulence, thus minimizing wear. The open bottom of our Sand Casting Heavy Duty Slurry Knife Gate Valve allows for the purging of large solids, and solids in higher concentration. The purging of solids stops when the gate is in the full open or closed position. Our Sand Casting Heavy Duty Slurry Knife Gate Valve is highly appreciated by the clients for high strength, durable life and resistance towards corrosion.

Features :

  • New and replaceable upper seal design is not only packing less, which eliminates the need for periodic adjustment, it is also a self lubricating system and is rechargeable without valve disassembly
  • Open bottom allows for the purging of large solids, and solids in high concentration
  • Bi-directional shutoff
  • Sleeves are available in a variety of materials to handle abrasion, and chemical application
  • Flushing plate option allows for periodic cleaning of the lower discharge vent and allows flushing as needed


Two-Piece Rubber Sleeve System : Port pressure provides assistance by forcing the sleeves against the opposing sleeve or the gate, depending on the position, to provide greater sealing force. Face rings allow the valve to cycle under maximum flow conditions up to a maximum differential of 150 psi10 bar. Seats are self gasketing and are compatibility with raise face.

Flushing Cover Bonnet : Flushing Bonnet attached to the bottom flange to capture any discharge during cycling. This option also allows for periodic cleaning of the lower discharge vent and can allow flushing as needed. It has a bi- directional shut – off design.
