• Quantum enclosures integrate position
sensors and low power solenoid valves into a
single unit.
• Solenoid coils integrated within Quantum
housing.
• Choice of factory pre-wired 3 and 4 way
Falcon solenoid valves.
• Solenoid valves with a choice of Cv ratings
and coil voltage.
• Strong durable BeaconTM offers 360° visual
indication in a choice of styles and colors.
• Touch set cams are hand adjustable, spring
loaded and self-locking providing quick
calibration of position switches and sensors.
• Terminal strips are pre-wired and numbered
for ease of use.
• Additional conduit for easy field wiring and
mounting accessories as standard.
• Standardized mounting pattern for easy
adaptation to common bracketry.
• Robust stainless steel conduit entry inserts
provide protection from excessive torque and
reliable grounding.

content (0.2% maximum) suitable for
corrosive environments.
• Rugged stainless steel enclosure.
General application
Quantum control monitors combine consistent
and accurate valve monitoring with the control
of automation process valves using integrated
position sensors and low power solenoid valves
in a single compact unit.
