Demanding applications such as gas turbine control require reliable operation in hazardous environments. Diakont’s industry-leading line of explosion-proof electric servo actuators are used to increase efficiency, safety, and reliability in the gas turbine industry for applications such as:• Inlet guide vane (IGV) control• Nozzle guide vane (NGV) control• Fuel valve control
Diakont’s electric servo actuators provide exceptional service lifetime while requiring minimal maintenance. Diakont’s linear and rotary actuator configurations both use advanced roller screw technology which ensures an operation lifetime of 20 years or more. Also, Diakont’s robust actuators only require re-lubrication maintenance once every four years.
Hydraulic systems have historically been used in the turbine control industry. However, hydraulic systems present issues of complexity, maintenance costs, and space challenges due to the need for auxiliary hydraulic components. Diakont’s electric servo actuators deliver a direct replacement for hydraulic systems and provide a more compact, more cost-effective, and safer solution.
