On October 31, 2025, Rotork announced the launch of the RTP - 4000 range, a new generation of intelligent valve positioners designed for single - and double - acting actuators on rotary and linear valves, with the dual - certified RTP - 4400 model taking the lead in its launch.

This positioner adopts magnet - based contactless position feedback, which gets rid of mechanical wear and ensures long - term reliability for both linear and rotary actuators. The advanced pressure sensor - based diagnostic system supports online real - time device status monitoring and predictive maintenance, and its user - friendly dashboard allows users to check the valve status at a glance.

Constructed of copper - free aluminium with electronic circuits potted in resin, the RTP - 4000 features corrosion resistance and ruggedness. It also has an arctic option that enables it to work at temperatures as low as - 55 °C. In addition, it has dual certification, making it applicable in both explosion - proof and intrinsically safe areas. Its high pneumatic capacity allows for rapid valve operation, and optimized supply air consumption reduces operational costs for customers.

Optional configurations include analogue and digital outputs, pressure gauges, as well as support for emergency shutdown applications with partial stroke testing capability. Juha Kivelä, Rotork's global product manager for pneumatic actuation and instrumentation, stated that the RTP - 4000 meets the needs of high - end process industries and upgrades the company's positioner product line, bringing customers the advantages of easy installation and long - term reliable operation.
