KNIFE GATE VALVES

Isolate the Flow in Demanding Conditions

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.

Flowrox offers three different models to best fit the chosen process: Slurry Wafer Knife Gate Valve (SKW), Slurry Flanged Knife Gate Valve (SKF) and High Pressure Slurry Knife Gate Valve (SKH).

  • Small face-to-face dimension

  • Available in large size scale

  • Low maintenance cost

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.

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

The SKH valves are available in sizes DN80–600.

Typical installations:

  • Tailings slurry lines

  • Slurry pump isolation

  • High-density slurry line

  • Ash slurry disposal
