STAFSJÖ XV

Stafsjö knife gate valve XV is delivered with either hand wheel, pneumatic, hydraulic cylinder or electric actuator. Pneumatic is also available as a single-acting actuator (spring open or close) or solution with accumulator tank for Fail Safe solution.

The knife gate valve provides a safe and tight shut-off regardless of the pressure direction. The valve has good flow properties and can be used in applications with cellulose, water and sludge. We also have a special version that expands the possible applications to abrasive media, slurry applications and often in combination with high pressures and temperatures. The valve is normally delivered in a stainless steel design, but is also available on request in high-quality materials such as SMO 254 or duplex.
