Description
Knife Gate Valve
The Knife Gate Valve is designed for reliable isolation in demanding slurry and bulk handling applications. Featuring a robust SG iron body and a semi-lugged wafer design, this valve ensures durability, corrosion resistance, and long service life in abrasive environments.
Equipped with dual replaceable elastomer sleeves, the valve provides bi-directional sealing, ensuring tight shut-off in both flow directions at maximum operating pressure. The full bore design allows unrestricted flow, minimizing pressure loss and improving system efficiency.
The smooth internal bore eliminates grooves and cavities where sediment or slurry can accumulate, reducing maintenance requirements. A protected spindle system, complete with a spindle cover and bellows, safeguards against contamination from splatter and harsh operating conditions.
Available in sizes from DN50 to DN600 with varying pressure ratings, this valve is ideal for industries requiring efficient flow control, abrasion resistance, and dependable shut-off performance.
