Disc Valve Hand Operated


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

Unlike many conventional 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; aluminium, cast iron and stainless steel. Pneumatic versions 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.
