COVNA explosion-proof electric actuators meet the needs of your fluid control applications. They are used in industries with hazardous environments, such as oil pipelines, natural gas pipelines and shipbuilding. Use them with your ball valve, butterfly valve, gate valve or damper to realize industrial automation and enhance the safety of your project.
Electrical actuators are an economical choice for a Hazardous Location, particularly where compressed air is not available or when it cannot meet the operating characteristics needed in a hazardous environment. An electric actuator in a properly classified enclosure provides the necessary operating characteristics for Class I, II, III or Division 1 Hazardous locations rated as gasoline, hexane, naphtha, benzene, butane, propane, acetone, benzol or lacquer-solvent vapors.
Compared to standard supervised solenoid actuators used in nonhazardous areas, the explosion proof design offers a simpler and more cost effective solution for most gaseous fire protection systems. This is especially true when limit switches – for position indication – are mounted and powered in a nonhazardous area and then piped to the actuator. Moog’s range of products for Hazardous Locations include Servomotors and Electro-Mechanical Actuators. Many of these are ATEX and IECEx certified so they can be fully integrated into your application. Explosion Proof 3-Piece Ball Valves
