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.

Constrction:

  • 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

Features:

  • There are no slide guides to jam or collect product
  • The shaft is the only item that passes through the body casting and is easily sealed using a proprietary seal assembly
  • A dovetail groove in the seating face locates another proprietary seal ensuring a dust tight closure of the Swing Gate Valve
  • A range of bore sizes are available from 100mm to 300mm, with the outlet always larger than the inlet, ensuring no product hang-up points internally
  • In-situ seal wear adjustment
  • Three Purge Points are built into the valve body for ease of cleaning

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

Benefits:

  • Non jamming action
  • Full Bore discharge
  • The Swing Gate Valve is able to cut through a static column of product
  • 100% product shut-off
  • Long life, low maintenance
  • Easy replacement of Disc seal
  • Dust tight
  • 316 stainless steel contact parts
  • Open, Closed and adjustable intermediate switches
  • Special switch/solenoid packages for hazardous locations
  • Special surface coatings on the Iris Valve to suit corrosive environments
