Rotork has announced the launch of the RTP-4000 range, a new generation of intelligent valve positioners designed to provide optimised control for single- and double-acting actuators on rotary and linear valves.
The launch begins with the dual-certified RTP-4400 model, which combines smooth installation and commissioning, advanced online diagnostics, robust construction, and seamless system integration for fast and energy-efficient operation. The range is ideal for demanding oil and gas applications as well as other industries requiring high-end valve control solutions.
RTP-4000 positioners feature magnet-based, contactless position feedback, eliminating mechanical wear and ensuring long-term reliability for both linear and rotary actuators. Advanced pressure sensor diagnostics provide real-time device status and predictive maintenance capabilities, while a user-friendly dashboard displays valve status at a glance.
The rugged, corrosion-resistant design includes copper-free aluminium and electronic circuits potted in resin for durability in harsh environments. An arctic option extends the operating temperature down to -55 °C. The positioner integrates easily with all major control and asset management systems, and dual certification allows use in both explosion-proof and intrinsically safe areas.
High pneumatic capacity enables rapid valve operation, while optimised supply air consumption enhances efficiency and reduces operational costs. Additional options include analogue and digital outputs, pressure gauges, and support for Emergency Shutdown (ESD) applications with partial stroke testing capability.
