CONTROL VALVE
PRESSURE CONTROL VALVE – LIQUID OR GAS
FLOW CONTROL VALVE – LIQUID OR GAS
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.
DO Based Aeration Control with diffused aeration and blowers
• Iris Valve Process Control for:
– Airflow based control
– Pressure based control
• Most Open Valve automated control types
• Ammonia-Based Aeration Control (ABAC)

EGGER IRIS® CONTROL VALVE SUCCESS STORIES
As Process Engineers begin changing their processes to “Low D.O.” and/or “ABAC” systems,
they have found that the Iris Valve is the only valve on the market which can provide
stable control at the high flows as well as at 5% or 10% Open (Low Flows).
Simply, Iris is the only valve with constant geometry from 0 to 100 percent.
