BD Iris Valve
The BD Iris Valve is a light duty valve specifically designed for infrequent operation, which can be used for both in-line and open discharge operations. The Mucon BD Iris Valve offers a double diaphragm for in-line applications, thus preventing material leakage to atmosphere. The valve are suitable for handling materials with bulk densities up to 560 Kg/m³. In addition, the BD has a simplified construction when compared to other Iris in-line valves. This simplified construction consequently offers the customer reduced cost, size and weight. For valve sizes between 50 mm and 200 mm, the Iris Valve body parts are manufactured from aluminium with a Gunmetal Control Ring. For valve sizes 250 mm to 300 mm, the valve is manufactured from aluminium and incorporates a zinc aluminium Control Ring. 50mm and 80mm valves are fitted with thumbscrew locking; all other sizes have nylon triggers and 316 stainless steel fasteners.
