The hydraulic control valve group mainly consists of a relief valve, an oil suction check valve, a speed control valve, a hydraulic control check valve (hydraulic lock), etc., and can also design oil circuit combination valves with different functions according to the working characteristics of the electrohydraulic push rod. Meet their job requirements. Generally, self-locking is introduced, and the self-locking and push-pull are self-locking; the running speed is adjustable, and the speed is not adjustable; the working angle of the electro-hydraulic push rod is horizontally pushed, pushing up (including oblique upward), pushing down (including oblique down) and so on. The hydraulic control valve group has the following main advantages:

(1) Compact structure, convenient installation, small space occupation and simple maintenance.
(2) It can be started with load and has overload protection function.
(3) The circuit is equipped with a two-way hydraulic lock, which can be stopped at any position within the specified stroke range and self-locking, and keep the output force unchanged.
(4) Push-pull force, speed (user requirements) steplessly adjustable, driving range is extremely wide.
(5) If the power is cut off, the push rod is self-locking to avoid accidents.
(6) Full hydraulic drive, sensitive action, stable operation, effective cushioning of external impact force, accurate stroke control (≥0.5mm)
(7) Electromechanical and hydraulic integrated fully enclosed structure, the working oil circuit is circulated in the closed steel cylinder without pressure, small in volume, no oil leakage, in the bad
In the working environment, no dust, no water, no internal corrosion, long service life.Learn more about rubber hose structure
