solenoid valve hydraulic oil circuit block Hydraulic oil block is an important part of the hydraulic system, it is mainly used for storage and transmission of hydraulic oil. In the hydraulic system, the hydraulic oil block plays the role of pressure transmission. When the system needs to generate power, the hydraulic oil block will be compressed, and the pressure will be transmitted to the components that need power through the oil pipe, thereby driving these components to work. At the same time, the hydraulic oil block can also play the role of lubrication and cooling system to protect the normal operation of the system。 Welcome to consult and visit our company Huaian Yansheng Hydraulic Co., Ltd.
