Wafer Knife Gate Pinch Valve for the Toughest Slurries and Abrasive Applications


The Flowrox 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

Bi-directional flow

Bi-directional flow tolerates backflow. 100% isolation.

Free flow

Full bore enables free flow of process medium.

Wear resistant

Only the ring sleeves in contact with the process medium.

Simple to install and service

Face-to-face according to industry standards. Contains only two service parts; ring sleeves and upper seal.

Typical installations:

  • Tailings slurry lines
  • Slurry pump isolation
  • Thickener feed and discharge lines
  • Flotation isolation

How EIM Actuators Improve Delayed Coker Operational Uptime

A Refinery’s delayed coking unit is not new technology, but is the most common process to upgrade the residual hydrocarbons remaining after upstream processing to remove water and soluble salts in the crude desalter; production of gasoline, diesel, jet fuel and atmospheric reduced crude through atmospheric distillation; and the production of heavy vacuum gas oil (HVGO) during vacuum distillation. The vacuum reduced crude remaining after these three stages becomes the principal feedstock for the next process stage – delayed coking.

Read this white paper to find out how EIM actuators helped this US refinery improve uptime and reduce cost.
