A water treatment facility in Olathe, Kansas, has deployed a novel solution to a valve access problem.

The gravity filter plant houses 18 butterfly valves in an area beneath a walkway, making access and operation of the actuators a complicated task. Recent rehabilitation work at the facility has included the installation of Rotork IQ3 intelligent electric valve actuators, replacing the electric valve actuators from a different manufacturer and helping address the access problem.

According to a Rotork statement, Remote Hand Stations (RHS) have been installed alongside the new actuators. These RHS provide an exact duplicate of the actuator switches, display window and control interface. The devices are mounted on the walkway to enable the user to safely operate, interrogate and configure the actuators below.

Each RHS is powered by the actuator, with which the unit shares all the benefits of the same O-ring sealed IP68 double-sealed environmental enclosure. Rotork claims that standard comms wiring suitable for the operating environment is all that is required between the actuator and the RHS, which can be installed at a distance of up to 100 metres (328ft) from the valve.

Using the Rotork hand-held setting tool with its secure wireless Bluetooth link, this information can be downloaded and transferred to a PC for analysis using Rotork Insight2 diagnostic software to fulfil asset management requirements.
