EHA-SY series electro-hydraulic actuators
EHA-SY series electro-hydraulic actuator is a domestic electro-hydraulic actuator developed by SCIYON based on autonomous controllable technology. The product integrates hydraulic, mechanical, electronic and control technology, integrates the simplicity of electric operation, the power of hydraulic, the reliability of solid state electronics and the flexibility of user configuration operation. And to minimize the technical shortcomings of commonly used pneumatic, electric and electro-hydraulic actuators, EHA-SY electro-hydraulic actuator has the advantages of fast response speed, large output power, high control accuracy, high power to mass ratio, and can freely choose switching type, regulating type, high precision and high frequency sound type, fast switching type, emergency shutdown type, etc. Suitable for steam turbine control, pipeline valve regulation and other occasions, used to replace a variety of pneumatic actuators, electric actuators, hydraulic regulation system with more rapid, more stable, easy maintenance and other outstanding advantages. Can be widely used in power, metallurgy, petroleum, chemical, light textile, mining, fire and environmental protection and other industries process control.
