Ibereolica’s Olivenza Thermosolar plant in Spain is using intelligent electric valve actuation with digital two-wire monitoring and control from Rotork for valve automation.

The plant is a concentrated solar power (CSP) technology facility that generates eco-friendly electricity for up to 50,000 households.

More than 100 IQ actuators and two Pakscan P3 hot-standby master stations have been supplied, fully installed, cabled and commissioned by Rotork Iberia.

The IQ actuator technology is used for isolating and regulating valve duties in the power generation industry.

Digital two-wire control is provided by Rotork’s Pakscan P3 system.

Key benefits of product application

  • Using solid-state electronics as an alternative to switch mechanisms and counter limiting devices, combined with programmable microprocessor-based control and instrumentation functionality, offers benefits including non-intrusive configuration and data transfer by means of a handheld instrument via a secure, bidirectional link.
  • Using the multi-lingual menu on the actuator display screen, it is quick and easy to commission the valve, with or without mains power connected.
  • The inclusion of a data logger in the actuator enables an event-by-event history of valve activity to be generated, including torque profiles produced during each opening and closing.
  • Rotork supplied IQ electric actuators with Pakscan digital control at Ibereolica’s first plant, Moron Thermosolar — installation and commissioning was performed on time and without incident, which led to the company choosing the same Rotork equipment for its second plant.
  • Pakscan combines high reliability and efficiency with low maintenance costs.
