DSS Soft Start Paste Valve

Cutting edge technology for Paste Backfill applications.

DSS Severe Service Knife Gate Valves represent the cutting edge in paste backfill valve technology because of our unmatched ability to isolate and control solids in suspension. Ranging from Class 150 (PN 20) to Class 900 (PN 150), our valves thrive at mining facilities around the world.

Our Soft Start Paste Valve has a modified gate that permits a reduced amount of material to flow through. By slowing the flow velocity and amount of paste in the pipeline until it is completely filled during start-up, the Soft Start Paste Valve removes the chance for catastrophic impact caused when paste descends vertically and reaches elbows, valves, or other instruments in the pipeline.
