DESCRIPTION

The QuickTrak (QT) system features the latest in pneumatic digital valve control technology that combines a icroprocessor-based control system with an integrated valve positioner. This system is specifically designed to answer the challenges faced by todays demanding applications.
Capable of providing the control and performance of a hydraulic system, but without the environmental and storage requirements; the QuickTrak™ system is flexible and powerful.

• Probe: Magnetostrictive linear position transducers located within the actuator stem which provide fast and highly accurate control feedback.
• 3-Way valves: Fail mode is done through (2) 3-way valves (SIL certified) piloted by the solenoid valve, which isolate the servo-valve from  the actuator. A 3rd valve removes any bleed when fail mode occurs.
• Solenoid valves: 24 VDC continuously energized, normally closed, to initiate  fail mode upon loss of air supply or  signal power. 
• Servo-valve: High-capacity servo-valve  for positioning
• Actuator: Custom designed with larger ports to utilize the higher CV and a gun-drilled stem to accomodate the feedback probe.
• Digital controller: Provides a multi-level, closed loop system based on the valve and spool position to control the stepper motor to adjust the actuators chamber pressure to achieve the desired valve position.
