Our Cast Knife Gate Valves are engineered to provide reliable on-off and throttling control in tough liquid slurry and dry material handling applications. With a one-piece cast body made from corrosion-resistant 304, 316, or 317 stainless steel, these valves ensure superior durability and resistance to abrasion. The gate material is also available in 304, 316, or 317 stainless steel, making them well-suited for corrosive and non-corrosive environments.
Heavy-duty Cast Body: Ensures corrosion and abrasion resistance, perfect for harsh conditions.
Supportive Cast Gate Guides: Located at 3, 9, and 12 o'clock, these guides provide extra durability and prevent breakage.
Positive Shutoff: The cast gate jams at the bottom of the body, holding the gate securely against the seat.
Full Reverse Pressure Rating: Ensures reliability even under high-pressure conditions.
Wide Size Range: Available in sizes from 2 Inch to 36 Inch (DN50-DN900), with options for metal or resilient seats.
Variety of Actuator Options: Choose from handwheels, chainwheels, bevel gears, levers, pneumatic, hydraulic cylinders, and electric motors.
Improved Flow Capacity: Full round-port design reduces pressure drop and ensures optimal performance.
Enhanced Sealing and Durability: The beveled knife-edge gate is designed to slice through solids in the flow stream, while the rounded edges reduce packing wear and extend service life. Precision-ground gates help prevent damage to the packing and seat, enhancing the valve's overall sealing performance. The robust construction is further complemented by a strong investment cast clip, adding to the valve's long-lasting reliability.
KOSEN Knife Gate Valves are the ideal choice for industries where high-flow capacity, minimal pressure drop, and superior sealing performance are critical. Available with a full complement of accessories, these valves can be customized for a wide range of applications, from heavy-duty industrial processes to precise flow control requirements.
