Iris Valve

Iris Valve

An iris valve is a precision flow control device named after its camera-iris-like mechanism. It is designed to regulate the discharge of powders, granules, and bulk solids under gravity flow conditions. The valve enables smooth, step-less adjustment of material flow without damaging the product. Iris valves are commonly installed at big bag unloading systems, bag dump stations, and hopper or bunker outlets to control flow rate and improve process stability. Their design helps minimize bridging, ensures consistent discharge, and enhances operational efficiency. With a compact structure, easy integration, and low maintenance requirements, iris valves are widely used in food, chemical, mineral, and bulk material handling industries.
Working Principle:

It is designed to control the flow of bulk solids, powders and granules and works by adjusting the flexible inner diaphragm to change the size of the opening. The flexible material in the body bends when the rotary lever is moved, cutting off the flow completely. When the handle is rotated, the valve body opens fully. In big bag unloading systems, the big bag is passed through the iris valve before the unloading port is opened and then the unloading port is opened. During the material flow, the iris valve can close the big bag discharge port to the desired extent and the material flow rate can be adjusted. If desired, the material flow can also be stopped completely.

Product Information
Iris Valve Features and Advantages:

Flow control of bulk raw materials in powder, granule or pellet structure is easily achieved. Iris Valve, which draws attention with its slim and space-saving body design, allows the flow rate to be adjusted in the desired shape and ratio. It can be supplied specially for application areas with valve connection flanges in accordance with DIN or ANSI norms. Replaceable valve sealing elements can be specially produced according to customer demand. Pneumatic piston, electric motor and manual turning lever options are available. It enables valve position monitoring with the help of limit switch and position indicator.
