Local Controls
Airflow control valve assemblies are often furnished with control loops special to the application. These control loops can be pneumatic or electronic & include transmitter, transducers & a local controller. We offer a variety
of each of the components, which can be combined
to fit the special needs of even the most critical applications.
Often we are called upon to furnish factory programs for applications requiring pressure independence maintaining space offsets.

Local Control Products
Our 873 fume hood controller provides local
monitoring & control of fume hood velocities.
Monitoring & control of the flow rate is
both accurate & repeatable.
Localized Damper Controllers (883)
The Local electronic controller is factory
mounted on the flow valve & provides
calculation & control of the space
terminal devices. Scan rates are faster
& pre-tested factory programs are available.
Averaging Differential Pressure (863/820)
For use with our 811 low leakage damper we
offer a control package to not only accurately
modulate the air flow but also an extra loop
to fully close & then open the damper for
space isolation. An additional "space scavange"
loop can be also be added.
