ELECTRO-HYDRAULIC VALVES – A TECHNICAL LOOK
To increase the spool actuation force the main spool of pilot operated valves is operated hydraulically by a pilot valve By hydraulically amplifying the electrical command signal pilot operated valves can reach very high spool actuation forces and thus be built up to very large rated flows |

Electro-hydraulic
Electro-hydraulic valve actuators Design Features Scotch yoke actuator in either double-acting or spring-return configurations Closed hydraulic muliti-function system (Reservoir sized per number of strokes required ) Operating pressure: Up to 350 bar Torque output: Up to 350000 Nm |
Electro-hydraulic systems combine the benefits of electrical signal processing with hydraulic drives to create versatile and reliable control systems.
These systems can be categorized into three groups based on functionality, each offering unique advantages and applications.
