Product catalog summary
Overview
DeZURIK Cast Knife Gate Valves (KGC) are designed for on-off and throttling applications, featuring a cast body and gate made from 304, 316, or 317 stainless steel. These valves are available in sizes ranging from 2 to 36 inches and offer both metal and resilient seated versions. Various actuator options are available, including handwheels, chainwheels, bevel gears, levers, pneumatic and hydraulic cylinders, and electric motors.
Design and Construction
The KGC valves have a one-piece cast, corrosion-resistant body suitable for handling tough liquid slurry and dry materials. The cast gate guides and jams provide support and ensure a positive shutoff. The lug body is designed with drilled and tapped lugs according to ANSI Class 125/150 dimensions. The full, round port design allows for high flow capacity and minimal pressure drop.
Gate and Sealing Features
The gates are available in stainless steel with a precision ground finish to prevent packing and seat damage. The beveled knife-like edge of the gate helps in cutting through solids, while the rounded edges increase packing life and provide a superior seal. The stuffing box and anti-extrusion ring enhance the packing system, reducing external leakage and minimizing friction.
Packing System
The KGC valves feature a high-performance packing system designed for long-life seals with minimal gland pressure. The system includes options for general, moderate, severe, and high-temperature applications, with various packing materials available based on temperature, pH, and media properties.
Seat Options
Both metal and resilient seated valves are offered. The resilient seated valves provide drip-tight shutoff and are designed specifically for knife gate applications. A variety of resilient seat materials are available, including chloroprene, acrylonitrile butadiene, and fluoro rubber.
Actuators and Accessories
A wide range of actuators and accessories are available to customize the valve/actuator package for specific applications. Options include purge connections, corrosion-resistant materials, lockouts, and hardened/removable seats.
Lockout Options
The KGC valves offer advanced lockout design technology to ensure safety and environmental protection. Unique designs are available for both manual and automated models, with a patent-pending lockout collar for automated models.

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 available...

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 40...

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 pushed...
