Rotork launches naval version of market-leading electric valve actuator
Valve actuation and control specialist Rotork has introduced a new version of its market-leading IQT intelligent electric actuator, developed specifically to meet the extreme demands of naval marine applications

Designated IQT-N, the actuator provides direct-drive operation of quarter-turn valves.  Expressly designed for the modern warship environment, the IQT-N has been independently tested for shock tolerance to meet the requirements of most worldwide surface ship applications.

The overall size of the actuator has been reduced in comparison to its non-naval counterpart to account for shipboard space constraints. The result is a low cost, reliable and lightweight ‘fit and forget’ valve control solution offering a multitude of options for the management of shipboard critical systems.

Available for three-phase, single-phase or DC power supplies the IQT-N embodies the same high level of features as the standard IQT.  Actuator setting and configuration is performed non-intrusively using a hand held setting tool and two-way infra-red link.  The integral data logger keeps an historical record of operating activity, including valve operating torque curves, which can be downloaded and analysed on a PC using Rotork IQ-Insight software to plan for maintenance or diagnose potential operating issues.  The same software enables all set-up and configuration information to be reviewed, re-configured and then uploaded back into the actuator.

Specifiable for isolating or modulating valve duties, the IQT-N features a robust construction with IP68 dust tight, watertight and temporarily submersible (7 metres depth for 72 hours) protection.  In addition to quarter-turn valves and dampers, special versions are also available for full-turn and multiport applications.  Other options include a fail-safe battery back-up system and fire protection exceeding ANSI/API607 and UL1709 (1093°C/2000°F for 30 minutes).
