Hydraulic valve is an automatic component operated with pressure oil, it is controlled

by pressure valve pressure oil, usually combined with electromagnetic pressure valve,

can be used for remote control of hydropower station oil, gas, water pipeline system.

Commonly used for clamping, control, lubrication and other oil circuit. There are direct

action type and pioneer type, multi-use pioneer type. According to the use is divided into

one-way valve and reversing valve. Check valve: only allow the fluid to be one-way connected

in the pipeline, and the reverse is cut off. Reversing valve: change the on-off relationship

between different pipelines. According to the working position of the valve core in the valve

body, the number of two, three, etc.; According to the number of controlled channels divided

into two, three, four, five, etc.; According to the spool drive mode, break up, motorized,

electric, hydraulic, etc. In the late 1960s, the electro-hydraulic proportional control valve

was developed on the basis of the above several hydraulic control valves. Its output

(pressure, flow) can be continuously changed with the input electrical signal. Electro-hydraulic

proportional control valves are divided into electro-hydraulic proportional pressure control

valves, electro-hydraulic proportional flow control valves and electro-hydraulic proportional

direction control valves according to their different functions.
