Structural performance

The hydraulic control valve assembly primarily consists of components such as the overflow valve, oil suction check valve, throttle valve (as per customer requirements), and hydraulic check valve (hydraulic lock). It can also be designed with different function oil circuit combination valves based on the operational characteristics of the electro-hydraulic actuator to meet its operational needs. Generally, there are self-locking features for pushing out, pulling back, and both pushing and pulling. Operating speeds include adjustable and non-adjustable types. The working angles of the electro-hydraulic actuator can be horizontal push, upward push (including diagonal upward), and downward push (including diagonal downward). The main advantages of electro-hydraulic actuators include:

(1) Compact structure, easy installation, small space occupation, and simple maintenance.

(2) Capable of starting under load with overload protection feature.

(3) The circuit is equipped with a two-way hydraulic lock, allowing it to stop at any position within the specified stroke range and automatically lock in place, while maintaining a constant output force.

(4) Push-pull force and speed (as per customer's requirement) are infinitely adjustable with a wide range of driving power.

(5) In case of power outage, the push rod will automatically lock to prevent accidents.

(6) Full hydraulic transmission ensures sensitive operation, smooth running, and effective shock absorption.行程control is precise (≥0.5mm).

(7) Integrated mechanical, electrical, and hydraulic full-sealed structure; oil circuit circulates within a pressure-free enclosed steel cylinder, featuring compact size, no oil leakage, and resistance to dust, water, and internal corrosion in harsh working conditions, with a long service life.
