Rotork Iqt - Part-Turn Shutdown Battery Actuator


In the event of mains power loss, the Rotork IQT Part-turn Shutdown Battery Actuator can continue to function automatically to a safe position. The failure mode can change depending on customer requirements. This fail-to-position can be fail-closed, open, stayput or go-to-a-per-cent position, depending on what is needed to ensure the process fails to a safe operating state. This prevents any safety issues and avoids monetary consequences due to loss of control.

The IQT Shutdown Battery also features an Uninterruptible Power Supply (UPS) mode. This ensures that there is continued control and operation of the actuator on loss of mains power until the battery charge has run out. Operations can continue as normal while the battery charge lasts, mitigating any risk of lost revenue or safety implications.

There are multiple potential applications for the IQT Shutdown Battery; it is ideally suited to unmanned applications which require further fail-safe functionality when power is lost. it is appropriate for applications on PSD/ESD valves such as well heads, blow down and well-head choke valves, line breaks and high/low pressure scenarios. The Shutdown Battery is also perfectly suited for the transfer of crude oil and valves at often unmanned natural gas custody transfer stations. It is a compact alternative to spring-return fail-safe actuators.

A lithium-ion battery supplies backup power from within the actuator enclosure. Housing the battery within the actuator enclosure means the actuator’s ingress protection and hazardous area classification (ATEX, ICEx, CSA and CSAus) is retained. The battery automatically charges from the actuator mains supply during normal service, so is time-saving and efficient. There won’t be any downtime when the battery is being charged.

The same functionality from existing IQT actuators is provided, including partial stroking, Bluetooth® wireless communication, site configurable speed setting and non-intrusive IP68 double sealed enclosure.

This part is from our extensive range of IQT Actuators in our Rotork Actuator range.
