Rotork offers an extensive range of electric, electro-hydraulic and fluid-power valve actuators and damper drives to meet virtually any power plant application.
Two of Rotork’s latest product offerings include wireless capability and technologically advanced control-valve actuators.
New wireless capability
Rotork’s Pakscan P3 modular control system now offers the addition of a network card option that enables electric power generation companies, including control-room personnel, to communicate wirelessly with Rotork IQ valve actuators throughout their facility.
The wireless capability operates on the 2.4 GHz frequency and has a line-of-site operating range of approximately 70 m inside and 1,000 m outside. It includes built-in web pages that provide an easy way for control-room operators to access and extract important asset management information, such as actuator data logger and configuration files, without having to manually download the information in the field.

To provide robust on-site communication, the wireless option operates a meshing system that ensures all nodes have the facility of at least two routes back to the master station. If the normal traffic route is blocked, the network will find another way to route the messages.
CVA actuators: Enhanced performance and asset management capabilities
The all-electric CVA control-valve actuators offer power plants the ability to improve process control accuracy and gain important asset management benefits for predictive and preventative maintenance in control-valve applications.
The new CVA electric actuator solves many of the shortfalls found in traditional pneumatic type control-valve actuators. Specific features of the CVA include advanced “dual sensor” technology that can hold repeatability and resolution to less than 0.1 percent while eliminating stick-slip and overshoot effects. The CVA’s precision provides users with a way to attain better control of the process variable. Through state-of-the-art electronics, the CVA provides many advanced features, including high resolution and repeatability, enhanced user-interface capabilities, comprehensive data logging and energy-saving operation. They are available in linear and quarter-turn actions and are suitable for a wide range of applications and process environments within various types of power plants. Furthermore, the CVA features an advanced, programmable method for fail-to-position protection.
For asset management, Rotork Enlight software provides a wireless, non-intrusive, Bluetooth communication link between the CVA actuator and a standard PDA device. This provides quick and easy actuator set-up and diagnostics capabilities. In addition, the CVA data logger provides an extensive record of historical, operational and maintenance-related data, such as valve torque profiles, dwell time logging and step response curves. That data can be easily downloaded locally via Bluetooth or remotely through optional Hart or Foundation Fieldbus communication links.
