The electric-hydraulic actuator input signal is an electrical signal

Output actuator power source for hydraulic oil, therefore, especially suitable for high-thrust, stroke and high-precision control applications. Often the main steam gate control system in large-scale power plants, in order to obtain high-thrust, electric-hydraulic actuator.shut off solenoid valve
Electro-hydraulic actuator and electric actuator, the hydraulic mechanism, so it has more thrust or push torque. But require more complex control of hydraulic pipes and the hydraulic system, hydraulic system such as the control of the hydraulic oil temperature, pressure, etc., also need to add oil and oil circulation. And pneumatic piston actuator, electric-hydraulic actuator hydraulic cylinder instead of a cylinder, hydraulic oil incompressibility, the response speed of up to lOOmm / s, faster than the pneumatic piston actuator stroke positioning accuracy, control accuracy high (up to 0.5), and its stroke can be very long (up to lm) the output push large torque (up to 60000Nm), the output force is large (up to 25000N).two position three way valve
