Westlock Controls Valve Position Monitors and Digital Positioners
Factory-direct selection of Westlock Controls AccuTrak position monitors, Quantum control units, and ICoT digital positioners for industrial valves.
AccuTrak Rotary Valve Position Monitors
Westlock AccuTrak 2007 and 3300 units verify rotary valve open and closed status. Spring-loaded Touch-Set cams enable tool-free switch setting within seconds. The Beacon 360 monitor delivers clear visual feedback from any angle. Low-copper aluminum housings resist harsh marine atmospheres.
- Calibration: Touch-Set cams
- Indication: Beacon 360 monitor
- Sensors: V3 SPDT mechanical
- Enclosure: aluminum or 316 steel
Quantum Integrated Valve Control Monitors
Westlock Quantum 2600 and 3600 monitors integrate sensors with internal solenoid valves. The compact design eliminates external tubing between switch and actuator. Sealed IP66/IP67 enclosures protect wiring from dust and moisture. Units meet ATEX and IECEx explosive area requirements.
- Design: integrated switch and SOV
- Solenoid: Falcon single/dual coil
- Ingress protection: IP66/IP67
- Approvals: ATEX, IECEx, NEC
ICoT and K20 Digital Valve Positioners
Westlock ICoT and K20 positioners regulate rotary and linear modulating valves. Non-contact Hall effect sensing eliminates linkage wear in vibrating piping systems. Frictionless spool valves deliver an operating life beyond two billion cycles. Units provide 4-20 mA feedback with HART protocol.
- Sensing: non-contact Hall effect
- Spool life: >2 billion cycles
- Protocol: 4-20 mA HART feedback
- Tuning: Touch-Start auto-calibration
Digital EPIC Position Transmitters
Westlock Digital EPIC D200 units generate continuous 4-20 mA position signals. Microprocessors execute Partial Stroke Testing on emergency shutdown valves. Diagnostic logs support safety interlock loops up to SIL 3 ratings. Engineers configure parameters via the local LCD screen.
- Output signal: 4-20 mA HART
- Diagnostics: Partial Stroke Test
- Safety integrity: up to SIL 3
- Display: local graphic LCD screen
Falcon Solenoid Valves and Proximity Switches
Westlock Falcon pilot valves operate single and double-acting actuators. Low-power coil engineering reduces energy demands on 24 VDC control loops. Hermetic Magnum XT-90 switches with rhodium contacts withstand aggressive atmospheres. Assemblies connect to Profibus and AS-Interface networks.
- Valve design: Falcon 3/2 and 5/2
- Power options: 24 VDC, 120 VAC
- Switches: hermetic Magnum XT-90
- Fieldbus: AS-Interface, Profibus
Diagnostics, Calibration and Maintenance Services
Engineering specialists provide field diagnostics, calibration, and overhaul for Westlock devices. Technicians carry out 4-20 mA loop configuration, Hall effect sensor alignment, and switch replacement. All scheduled maintenance procedures adhere to rigorous industrial engineering standards.
- Services: calibration and overhaul
- Diagnostics: 4-20 mA and HART loops
- Alignment: Hall sensors and cams
- Contract terms: engineering standards
Engineering Architecture of AccuTrak Position Monitors
Westlock Controls AccuTrak rotary position monitors verify the status of automated process valves in harsh environments. The assemblies incorporate Touch-Set spring-loaded cams that permit tool-free switch adjustment within seconds.
A high-visibility Beacon 360 visual monitor gives operators an unobstructed view of valve opening angles from considerable distances. Heavy-duty enclosures manufactured from low-copper aluminum or CF8M stainless steel carry global explosionproof approvals including ATEX and IECEx.
Standardized NAMUR output shafts enable direct coupling to pneumatic actuator pinions without custom mounting adapters.
Operational Principles of ICoT Digital Valve Positioners
Westlock Controls ICoT and K20 digital positioners deliver precise modulation for rotary and linear control valves. Advanced non-contact Hall effect sensing measures valve travel without mechanical linkages or potentiometers that degrade under high vibration.
The patented frictionless spool valve assembly operates reliably for more than two billion cycles without pneumatic seal deterioration.
Standard units feature 4-20 mA current loop feedback with HART digital communication, supporting real-time valve diagnostics, predictive health monitoring, and remote configuration from the plant control room.
