Product Category: Valve Switch Boxes

Westlock valve switch boxes are manufactured to fit to both rotary and liner valves. They offer an integrated switch box for the monitoring of rotary process valves. They combine combining switches / sensors, wiring terminals, enclosures and local visual indication in one compact unit.

Digital EPIC – D200 Transmitter

Accurate digital valve position feedback with advanced diagnostics for hazardous-area automation.

The Digital EPIC D200 transmitter provides precise 4–20 mA position feedback with HART® 7 communication, improved linearity and reduced hysteresis in a compact, explosion-proof or intrinsically safe enclosure. A clear LCD screen, push-button auto-calibration and a standard non-contact position sensor simplify commissioning and support reliable long-term operation. With options for hermetically sealed Magnum switches, NAMUR sensors and integral Falcon V solenoid valves, the D200 delivers a versatile platform for monitoring and control across a wide range of rotary and linear valves.

For technicians and engineers, this means faster calibration, improved diagnostics and higher position accuracy.

Accutrak – 3300 Valve Switchbox

Intrinsic safety, reliable valve position monitoring and long-term durability for demanding industrial environments.

The AccuTrak 3300 rotary position monitor provides accurate valve position feedback in a compact unit certified for intrinsically safe (ATEX/IECEx) applications. With a 360° Beacon™ visual indicator, hermetically sealed Magnum switches, and inductive NAMUR sensors, the AccuTrak series delivers dependable feedback even in corrosive or hazardous areas. Pre-wired terminals, additional conduit entries and standardised mounting patterns simplify installation and wiring. Resin, aluminium or stainless-steel housings offer strong protection against chemicals, moisture and mechanical impact.

For technicians and engineers, this means safer operation, faster setup and reduced maintenance in all rotary valve applications.

Quantum – 789 Rotary Control Monitor

Reliable valve position monitoring and actuation control for hazardous-area automation.

The Quantum 789 rotary control monitor provides accurate valve position feedback and integrated low-power solenoid control in a compact, Division 2 certified enclosure. With a high-visibility Beacon™ indicator, hermetically sealed proximity switches and pre-wired terminals, it helps instrumentation teams reduce installation time and improve long-term reliability. Integrated 3-way and 4-way Falcon solenoid valves support dependable actuator control without external piping, while durable aluminium or stainless steel housings ensure performance in corrosive environments.

For technicians and engineers, this means faster commissioning, reduced maintenance and clear real-time valve status.
