IRIS® Measurement Regulation System
Constant Pressure & Flow Regulator
PRESSURE CONTROL – LIQUID OR GAS
FLOW CONTROL – LIQUID OR GAS
High Performance Constant Pressure & Flow Regulator
Available Sizes: 1″ – 16″
Pressure: up to 87 psi higher upon request
Temperature: up to 248 higher upon request
For fast, accurate and repeatable measurement and control of gases and liquids. The high-precision and fast-response mass fl ow measurement with sensor in the center of the flow axis guarantees precise and reproducible measured values without correction. Retractable segments in the housing allow free flow when the valve is fully open, ensuring low pressure losses and high energy-saving potential.
Energy Cost Saving and Low Noise Emissions
Due to the free passage and low turbulence in our Constant Pressure & Flow Regulator, 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
These 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 flow regulator may be used for liquids, gases, granules or powders. Available with integrated flow measurement for gases.
EGGER TURO PUMPS N.A. imports the Iris technology from Emile Egger & Cie SA, and we assemble our packaged system in Juliette, Georgia. Our monitoring & control system is comprised of the following components:
- Iris technology (purchased from Switzerland).
- AUMA gear-drive electric actuator (U.S. manufactured in Canonsburg, Pennsylvania).
- Kurz thermal mass flow meters (U.S. manufactured in Monterey, California).
- Felker Brothers piping (U.S. manufactured in Marshfield, Wisconsin).
- Final assembly & calibrated in Juliette, Georgia.
EGGER TURO PUMPS N.A. is the only manufacturer in the world who designs, builds, & markets Iris Measurement & Control System.
We ensure domestic component costs exceed 55% of the cost of all components. Therefore, no federal waiver is required in association with the use of solutions.

CONSULTING ENGINEERING PARTNERS
As Process Engineers begin changing their processes to “Low D.O.” and/or “ABAC” systems,
they have found that the IRIS Flow Regulator is the only product in 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 flow regulator with constant geometry from 0 to 100 percent.
1947: Swiss Engineered Pumps
EGGER, founded by Mr. Emile Egger, is an independent family-owned Swiss pump manufacturer specializing in handling solids and aerated liquids.
A key quality feature is that the whole production process – from development through functional testing – is carried out in-house under controlled conditions by 350 skilled employees.
Thanks to the contribution of each member of our team, we have succeeded in maintaining our excellent level of quality; the highest even by typical Swiss standards.
Our unique background has been achieved by our ability to identify with and listen to each of our business partners. These partners have many different specific needs, however, all can be sure of
one thing: EGGER has the unique solution for them.
