IRIS Air Flow Control Valve
1442080-0-irissequence

High Performance Valve

Available Sizes: 1″ – 16″
Pressure: up to 87 psi higher upon request
Temperature: up to 248 higher upon request

Energy Cost Saving and Low Noise Emissions

Due to the free passage and low turbulence in our valve, energy costs and noise emissions are reduced to a minimum.

Rugged, Heavy Duty Construction

Designed for continuous operation, particularly suitable for variable duties. Simple installation and commissioning.

Non-clogging and self-cleaning

Due to the free, central flow design and automatic self-cleaning feature of the segment edges during valve operation Flushing connections are provided.

Several actuator designs available

Electrical actuator for precise regulation permitting up to 1200 operations per hour. Optional pneumatic actuator, hand wheel or lever.

Hysteresis-free and excellent regulation characteristics

are the prerequisites for regulating tasks. This is achieved by the continually variable aperture from 0-100%, similar to the IRIS diaphragm of a camera, always maintaining a central flow axis and by an enhanced segment edge design.

Various fields of applications

The iris flow control valve may be used for liquids, gases, granules or powders. Available with integrated flow measurement for gases.
