QT QuickTrak System features the latest in pneumatic digital valve control technology, that combines a microprocessor-based control system with an integrated valve positioner. This system is specifically designed to answer the challenges faced by todays demanding applications.

Flexible and powerful, capable of providing the control and performance of a hydraulic system, but without the environmental and storage requirements.

  • 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 two 3-way valves (SIL certified) piloted by the solenoid valve, which isolate the servo-valve from the actuator. Another 3-way 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.
