Rotork has launched the RTP-4000 range, a new generation of intelligent valve positioners designed to deliver optimised control solutions for single- and double-acting actuators on rotary and linear valves.
Launching with the dual-certified RTP-4400 model, this initial release combines smooth installation and commissioning, premium online diagnostics, robust construction and seamless system integration for fast and energy-efficient operation in demanding oil and gas applications.
The range features magnet-based, contactless position feedback, eliminating mechanical wear and ensuring long-term reliability for both linear and rotary actuators.
Advanced pressure sensor-based diagnostics provide real-time online device status and predictive maintenance capabilities, while a user-friendly dashboard offers at-a-glance valve status.
The rugged, corrosion-resistant construction, featuring copper-free aluminium and electronic circuits potted in resin, ensures durability even in harsh conditions, with an Arctic option extending the temperature range down to -55°C.
The positioner integrates easily with all major control and asset management systems, and the dual certification enables use in both explosion-proof and intrinsically safe areas. High pneumatic capacity enables rapid valve operation, while optimised supply air consumption helps customers to achieve greater efficiency and lower operational costs.
Additional options include analogue and digital outputs, pressure gauges, and support for Emergency Shutdown (ESD) applications with partial stroke testing capability.
Juha Kivelä, Global Product Manager – Pneumatic Actuation and Instrumentation at Rotork, said: “With the RTP-4000, we are meeting the requirements of high-end process industries and extending our already comprehensive Rotork positioner offering to the next level.
“Our customers will benefit from smooth installation, user-friendly online diagnostics and rugged construction, providing long-term reliability. The smart design features will help achieve greater operational efficiency and give peace of mind in even the most challenging applications.”
