Mucon Iris Diaphragm Valve – Why It Works

Mucon's Iris Diaphragm Valve

June 18th, 2018

How the Mucon Iris Diaphragm Valve WorksMucon, the inventor of the original Iris Diaphragm Valve, offers a full range of Flow Control Valves for use in controlling the flow of powders and granules in the pharmaceutical, chemical, and food industries. The valves are used worldwide for their superb flow control characteristics and versatility. Available in manual, pneumatic and electric operation the dust tight design allows for infinite flow control from full bore to trickle feed. The Mucon Iris Diaphragm Valve comes in a variety of materials suited to any application and is easily cleaned with tool-free maintenance.

How It Works

A tube of flexible material, the diaphragm, is manufactured with built-in retaining rings at each end. One end is held in position while the other is rotated 180°. The rotation completely closes the orifice providing equivalent load support of up to 100lbs/ft3. The closed diaphragm resembles the iris of a camera, hence the iris in Iris Diaphragm Valve.

Precision Control

For the precise flow control of powders and granules passing through the Iris Diaphragm Valve, add an optional Pulse Counting Trickle Positioning Proximity Sensor in conjunction with a notched ‘pulse’ ring on the output shaft of the gearbox for pneumatic or electric models.
