Process Systems carries a complete line of flow control
valves manufactured by Egger.
With pressures ranging from 44psi up to
85psi and temperatures up to 250F, the Egger Iris valves
are capable of handling a broad range of applications.
BS - Characteristics
Robust construction: designed for
continuous operation, particularly suitable for various
duties. Simple installation and commissioning.
Hysteresis-free and excellent regulation characteristics:
are prerequisits for regulating tasks. This is achieved
by the continuously variable aperture from 0 - 100%,
similar to the IRIS diaphragm of a camera, always maintaining
a central flow and by an enhanced segment edge design.
Non-clogging due to the free, central flow design and
the automatic.
self-cleaning feature of the segment edges during valve
operation. Flushing connections are provided..
Electric actuator for precise regulation
permitting up to 1200 operations per hour, S4-25% ED;
optional pneumatic actuator also available.
Examples of applications:
air, sugar, suspensions, sewage, sludge, paper stock,
drinking water, etc.
Energy cost savings and low noise emission through enhanced
design. Fixed throttling apertures and imprecise regulating
methods cause unnecessary pressure losses and energy
costs. Due to the almost free passage and low turbulences
in our valve these are reduced to a minimum. Because
of an advantageous basic characteristic, we can operate
in an energy saving manner, i.e. with optimal valve
apertures.

BS - IRIS regulating
valve with integrated flow measurement system
The collaboration between EGGER and the ABB company
allows us to offer our clients a simple and compact
solution. Thanks to the centered flow and the leveled
edges of the orifice, the compact SENSYFLOW measuring
system of ABB Automation can be directly installed at
the entrance of the valve. The measuring principle is
based on the mass of the gas, thus rendering the system
independent of the pressure and temperature of the gas.
The assembly of the IRIS regulating valve and the gas
flow measuring system SENSYFLOW does not need a straight
run, neither on the inlet nor on the outlet side, but
in that case it has to be calibrated on the certified
test bed. Our supply includes for a German Service Test
Certificate of Calibration (DKD).
