Rotork Supplies Electric Actuator for Valve Control on Gas Turbine Preheating Equipment

(January 3, 2012) Rotork’s CVA electric actuator has been specified for critical valve-control duty on high-temperature gas turbine pre-heater equipment supplied to the power-generation industry. The CVA actuators have been installed on seven skid-mounted units supplied to Riyadh PP11, a power plant project serving the capital city of Saudi Arabia. According to Rotork, the application demands unrestricted modulation of a three-way valve to control the preheated temperature of fuel gas for electricity-generating turbines. Manufactured by Petrogas Gas Systems in The Netherlands, the units heat the gas on its way to the turbines by passing it through a chamber surrounded by an oil bath that is heated to a temperature of 185ºC. Key benefits of product application: Using a 4–20mA control signal, each actuator moves a valve to control heat output Actuators are said to provide precise and responsive valve positional control Feature repeatability and resolution at less than 0.1 per cent Atex-certified and explosion-proof Double-sealed CVA design provides permanent environmental protection to IP68 Integral data logger facilitates valve diagnostics with predictive maintenance capabilities
