Able has developed a universal valve-position transmitter (V-TRAK) that can be retrofitted to most Xmas-tree valves to provide a 4-20mA output correlating to the mechanical valve position.

The V-TRAK, which requires no maintenance once installed, is a compact and lightweight mechanical instrument suitable for installation on common types of Xmas tree valves to replace basic limit switches or unreliable and high maintenance pressure transmitters.

Limit-switch technology only provides valve status as fully open or fully closed, rather than delivering continuous feedback of actual valve position during operation.

Alternatively, a pressure transmitter infers the position of the valve through monitoring the hydraulic lines to the valve actuators.

However, accuracy of the pressure measurement versus valve position is poor, as is reliability due to potential transmitter blockage that requires maintenance to rectify.

The obvious benefit of Able’s low-cost valve position transmitter is an output based on the actual valve position, not inferred, which is both accurate and repeatable.

Trending can also be used on valve operation speed to predict valve failure.
