The strongest and most resilient of the Mucon powered Iris valve range are the Series E Iris Diaphragm Valves. They have an extremely robust construction and reliable drive elements making it suitable for the hardest of tasks. The drive is provided by a powerful pneumatic piston and pulley system.

Body parts are made from aluminium, with a Gunmetal Control Clamp Ring
316L stainless steel fasteners are fitted as standard

For use on the outlets of Silos that handle heavy bulk solids. E.g. Sand, Cement, Lime Powder etc. Linked to weigh scale set points for ‘bagging off’
For use in controlling (not shut off) air flow ventilation ducting
Use for Big Bag discharge where automatic actuation is needed
Used for In-Line applications with no leakage to the atmosphere

316 stainless steel contact parts can be supplied on the Iris Valve
Pre-piped and directly mounted pneumatic control on the Iris Valves
Open and Closed control solenoid valve (Customer to specify voltage required)
Full trickle-feed facility, including trickle-feed switch and solenoid valves to give Open, Closed and adjustable trickle-feed position
Special cylinder and proximity sensors where the valve is required for ATEX zone 22D
In case of air or electrical failure Automatic closure system can be offered Special packages are available to suit hazardous environments
A variety of surface coatings to suit corrosive locations

Ability to handle and control the flow of very dense materials
It is Non jamming There is no leakage into the atmosphere
Full bore opening -Therefore, no product flow restriction
Suitable for frequent operation Quick closing – and ideal for weighing applications

Double diaphragm Iris Valve is perfect for in-line applications with no leakage in to the atmosphere
The robust construction makes the Series E Iris Valves suitable for handling products in excess of 1600 Kg / m³ In-situ diaphragm adjustment
The internal bearings and high quality materials enable frequent operation
Series E Iris Valves have a wide diaphragm selection to suit many specific applications
Bore sizes from 150mm to 450mm
