No need to remove the valve to replace the inner parts Suitable for difficult products in arduous environments, fitted with a pneumatic cylinder actuator for remote operation

Overview

The Mucon® Disc Valve is a radially pivoting isolation swing gate valve suitable for applications involving temperature and pressure. The advanced version easy maintenance disc valve, which allows the removal of the internal moving parts while the valve body remains in place. The inlet liner is separate and does not even have to be made from the same material as the valve body. Unlike many slide valves, the disc valve does not jam or leak, due to its unique angled seat and floating disc arrangement. The easy maintenance disc valve is available in 100mm & 200mm sizes only constructed of three materials; aluminum, cast iron and stainless steel. Hand lever operated versions also available. Customers have told us of disc valves (swing gate valves) completing many thousands of operations before any attention is required. The swing gate valve a valve specification which encompasses all the advantages found in slide and butterfly valves, but with none of the 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.
