ProportionAir ISQB1 Installation & Maintenance Instructions Manual

INSTALLATION & MAINTENANCE INSTRUCTIONS
DESCRIPTION / IDENTIFICATION
The ISQB1 series control valve is an electronic
pressure regulator
proportionally control the pressure of gaseous media
based on an electronic control signal.
The ISQB1 operates using two normally closed
solenoid valves, a pressure sensor, and a control
circuit. One valve is actuated to allow supply media
into the system. The second valve is actuated to allow
working media to vent through a threaded port to
atmosphere. The pressure sensor provides feedback
to the control circuit. The control circuit compares the
pressure sensor feedback to the user supplied
electronic command
appropriate valve until the two signals match.
The ISQB1 series can be teamed with a variety of air
piloted pressure volume boosters for even greater
flow.
