KGC CastStainless Steel Knife Gate Valves >

DeZURIK Cast Knife Gate Valves (KGC) are designed for on-off and throttling applications. They feature a cast body in 304, 316 or 317 stainless steel. The gate material is 304, 316 or 317 stainless steel. The packing gland is stainless steel for corrosion protection or coated carbon steel for noncorrosive service. The stem is stain- less steel. The yoke is available in 316 stainless steel for corrosive service or carbon steel for noncorrosive service. KGC Knife Gate Valves are available in sizes 236" (50֖900mm) with metal or resilient seated versions.A variety of actuator options are...

Cast Gate Guides and Jams > The cast gate guides at 3, 9, and 12 oclock provide support for the moving gate and will not break off like welded guides. Cast gate jams at the bottom of the body hold the gate securely against the seat to assure positive shutoff. All valves are rated for full reverse pressure in the closed position. Lug Body > Raised-face body has drilled and tapped lugs in accordance with ANSI Class 125/150 dimensions. High Flow Capacity > Full, round port design allows high flow capacity and minimum pressure drop. DeZURIKҒs KGC valve seat I.D. is equal to the I.D. of schedule...

Anti-extrusion ring guides the gate, makes the packing work better, reduces friction and acts as a gate wiper. The stuffing box is machined relative to the seat minimizing seat and external leakage simultane- ously. Optional live loadedӔ packing energizes the TFE braid while providing an extra tight elastomeric seal. The stem has fine pitch to maximize mechanical advantage.Strong Investment Cast Clip > MSP SMP ASP HMP Basic all TFE braidTFE braid with Anti-extrusion RingTFE braid with Anti-extrusion Ring & Energizing CordCeramic braid with Copper Scraper Ring >

Seat Options > Both metal and resilient seated valves are offered in a full, round port design. The integral metal seated version is available with shutoff capability exceeding current TAPPI TIS 405-8 and MSS- SP81 standards. Resilient Seated Valves > Resilient seated valves are available for applica- tions where drip-tight shutoff is required. Unlike valves which use an o-ring seal, DeZURIK Knife Gates have a resilient seat designed especially for knife gate valve applications. The resilient seat material is bonded into a stainless steel seat ring. When the valve is closed, the gate is...
