On 29 October 2025, Rotork unveiled its new generation of intelligent valve positioners — the RTP-4000 range — launching with the dual-certified RTP-4400. The range provides optimized control for single- and double-acting actuators on both rotary and linear valves, targeting demanding oil and gas applications and other high-end process industries.

Key Features:

· Magnet-based contactless position feedback: no mechanical wear, suitable for both linear and rotary actuators, with stable long-term accuracy;
· Pressure sensor-based online diagnostics: real-time device status supporting predictive maintenance;
· User-friendly dashboard: valve status at a glance;
· Rugged construction: copper-free aluminium housing with resin-potted electronics for corrosion resistance; an Arctic option extends the operating temperature range down to -55 °C;
· Dual certification: a single device approved for both explosionproof and intrinsically safe areas;
· System integration: compatible with all major control and asset management systems;
· Efficient pneumatics: high pneumatic capacity for rapid valve operation, with optimized supply air consumption for lower running costs;
· Extensive options: analogue and digital outputs, pressure gauges, and ESD support with partial stroke testing.

Juha Kivelä, Rotork Global Product Manager – Pneumatic Actuation and Instrumentation, said: "With the RTP-4000, we are meeting the requirements of the high-end process industries and extending our already comprehensive Rotork Positioner offering." "The smart design features will help to achieve greater operational efficiency and give peace of mind in even the most challenging applications."
