Heavy duty slurry knife gate valve isolates flow even in the most demanding process conditions. The bi-directional flow tolerates backflow and elastomer sleeves on both sides of the gate provide tight shut off. Flowrox knife gate valve follows the concept of the ease of maintenance. The valve body is cast in one piece which eliminates the need for sealing between the body halves. Load distribution ring is integrated into the valve sleeves. The valve contains only two service parts; ring sleeves and secondary seal.
Slurry Wafer Knife Gate Valve (SKW)
Slurry wafer knife gate valve (SKW) is designed for heavy duty purposes to isolate flow, even in the most demanding process conditions. The complete valve is built around an ease of maintenance concept and it contains only two service parts: ring sleeves and secondary seal.
Improved performance – Integrated load distribution ring
Ease of maintenance – Universal tower design
Simple installation – One peace body with lockout pins
Typical installations:
Tailings slurry lines
Slurry pump isolation
Thickener feed and discharge lines
Flotation isolation
The SKW valves are available in sizes DN50–600.
Slurry Flanged Knife Gate Valve (SKF)
Slurry flanged knife gate valves (SKF) are equipped with flanges. They isolate the flow even in the most demanding process conditions. They contain only two service parts: ring sleeves and a secondary seal.
Improved performance – Integrated load distribution ring
Ease of maintenance – Universal tower design
Simple installation – One piece body with lockout pins
Typical installations:
Tailings slurry lines
Slurry pump isolation
Thickener feed and discharge lines
Flotation isolation
The SKF valves are available in sizes DN80-600.
New Design for Big SKF Valves
Knife gate valve actuator cylinders repositioned to the side. Neles has repositioned actuator cylinders to the side in bigger slurry knife gate valves over DN 900. The benefits are:
Significantly reduced height – Easier to install, much less empty room above the valve is required.
Increased safety – Installation and maintenance is not done high in the air.
Easier maintenance – All maintenance access points are easily accessible, only 2 meters high from the ground.
Available in sizes from DN 900 to DN 1500. They can handle pressures from 10 and down to 4 bar, depending on the size. Flange drillings PN10 or ANSI 150, others on request. The actuator can be either hydraulic or electric.
Entire Valve Body Cast in One Piece Flowrox slurry knife gate valve body for sizes DN 900 – DN 1500 is entirely cast in one piece. This means there are no risks for leaking through the body. The new valve construction is simpler and more robust. Fewer parts also mean savings in spare part inventory and maintenance time.
High Pressure Knife Gate Valve for Slurries (SKH)
Isolate the flow even with 20 bar pressure. Slurry knife gate valve (SKH) is designed for higher pressures (up to 20 bar) in heavy duty purposes to isolate the flow. Just as previously presented SKW and SKF valves, SKH valves also contain only two service parts: ring sleeves and gland packing.
Ease of maintenance – Universal tower design
Simple installation – One piece body with flushing ports
