The pressure control valve is to control the oil pressure in the hydraulic system to meet the different needs of the actuator for the output force, output torque and motion state. It uses the balance principle of liquid pressure and spring force to work, and realizes and improves the performance of the system such as pressure regulation, pressure preservation, pressure reduction and pressure regulation.

This type of valve is mainly to control the oil pressure in the hydraulic system to meet the needs of the actuator for output force, output torque and different motion states. According to the principle of spool stress balance, the valve opening is adjusted to change the liquid resistance, so as to achieve the functions of pressure regulation, pressure preservation, pressure reduction, pressure regulation, or the use of pressure changes to achieve the sequential action of the actuator.

The flow control valve mainly controls the flow through the valve by changing the size of the flow area of the valve port in the hydraulic system. Thus, the movement speed (or speed) of the actuator (hydraulic cylinder or hydraulic motor) can be adjusted and controlled.

Flow control valve is mainly in the hydraulic system by changing the size of the valve port flow area or the length of the channel to change the liquid resistance, control the flow of the valve. Thus, the movement speed (or speed) of the actuator (hydraulic cylinder or hydraulic motor) can be adjusted and controlled.

Direction control valve is mainly used to control the oil circuit in the hydraulic system or change the direction of oil flow. Thus, the start or stop of the hydraulic actuator is controlled, and the direction of motion of the actuator is changed to meet the requirements of different working conditions.

The direction valve is used to make the oil circuit in the hydraulic system off or change the flow direction of the oil, so as to control the pneumatic or stop of the hydraulic actuator and change the direction of the movement of the actuator. On the basis of the YUKEN series of directional valves, the company has successively developed a variety of new products such as reversing valves with emergency handles and reversing valves with position monitoring to meet the requirements of different customers under different working conditions
