Rotork RTP-4000 series intelligent valve positioners

Rotork has announced the RTP-4000 range of intelligent valve positioners designed to deliver optimised control solutions for single- and double-acting actuators on rotary and linear valves.

The range features magnet-based contactless position feedback, eliminating mechanical wear for longer-term reliability for both linear and rotary actuators.

Pressure sensor-based diagnostics provide online real-time device status and predictive maintenance capabilities, while a user-friendly dashboard offers at-a-glance valve status.

A rugged, corrosion-resistant construction, featuring copper-free aluminium and electronic circuits potted in resin, aims to provide durability in harsh conditions, and an arctic option extends the temperature range down to -55°C.

The positioner integrates easily with all major control and asset management systems, and the dual certification enables the use in both explosion-proof and intrinsically safe areas.

High pneumatic capacity enables rapid valve operation, and optimised supply air consumption helps customers to achieve greater efficiency and lower operational costs.

Additional options include analog and digital outputs, pressure gauges, and support for emergency shutdown (ESD) applications with partial stroke testing capability.
