The Mucon® Disc Valve is a radially pivoting isolation. The swing gate valve appropriate for applications involving temperature and pressure. Unlike many slide gate valves, the Disc Valve does not jam or leak, due to its unique angled seat and floating disc arrangement. There are five bore sizes available with three main construction materials; aluminum, cast iron and stainless steel. Pneumatic versions are also available.

A radially pivoted arm supports a free floating disc. The arm allows the disc to swing in an arc towards an angled seating face. The angled face ensures the disc only makes contact at the last moment causing a mild wedging action.


  • Constructed from three materials including aluminum alloy, cast iron and stainless steel (stainless steel not available in 300mm bore)
  • Flanges drilled to BS4504 PN10- PCD & No. of holes only, not hole size


  • Silo Discharge valves for Heavy duty products such as cement powder, limestone powder and sand
  • Isolation valves between silos and screw conveyors
  • Valves for feeding reactor vessels (two products react together)
