BD Series Iris Valve
Ideal for light duty in-line applications where hand operation is required
The Series 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.
They are suitable for handling materials with bulk densities up to 560 Kg / m³.
In addition, the BD offers a simplified construction when compared to other in-line valves in the Mucon range. This simplified construction consequently offers the customer reduced cost, size and weight.
Construction:
- For valve sizes between 50mm and 200mm, the Iris Valve body parts are manufactured from aluminium with a Gunmetal Control Ring
