Mucon Disc Valve Pneumatic Actuator

A range of pivoting Disc / Swing Gate valves for sticky or difficult products in arduous environments, fitted with a pneumatic cylinder actuator for remote operation


The Mucon Disc Valve is a radially pivoting isolation Swing Gate Valve suitable for applications involving temperature and pressure.

Unlike many conventional slide 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; aluminium, cast iron and stainless steel. Hand lever operated Swing Gate Valves are also available.

Customers have reported Disc Valves completing many thousands of operations before any attention is required.

Born out of a valve specification which encompasses all the advantages found in slide and butterfly valves, but with none of the inherent disadvantages.

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.


  • Three materials of construction 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


Applications for Swing Gate Valves include:

  • Silo Discharge valves for Heavy duty products such as Cement Powder, Sand, Limestone powder
  • Isolation valves between silos and screw conveyors
  • Valves for feeding reactor vessels (Two products react together)
  • Hot ash collection hoppers
  • Valves can be used in pairs for volumetric dosing into processes
  • Charging dense phase conveying blow pots


Swing Gate Valves offer the end user great versatility, as they can be enhanced with the use of:

  • A variety of seal materials to suit the most arduous process or clean down regimes
  • A variety of shaft bearing materials
  • Various coatings are also available for extreme applications
