Description:

Working Principle: Proportional valve is to replace the original control part with proportional solenoid on ordinary pressure, flow and directional valves to continuously and proportionally control the pressure, flow or direction of the oil flow over a long distance according to the input electrical signal. In KDG4V-3-33C30X-M-U-H7-60, KDG4V indicates the series number, 3 indicates the three-position four-way, 33 indicates the center function, C30X indicates the flow specification, M indicates the spool form, U indicates the sealing form, H7 indicates the form of mounting surface, and 60 indicates the design number. The proportional valves are suitable for working pressures up to 350 bar (5000 psi) and flow rates up to 375 l/min (99 USgpm).

Areas of application:

Industrial automation: In various automated equipment for industrial production, such as packaging machinery, printing machinery, electronic manufacturing equipment, etc., it is used to accurately control the speed, direction and position of the movement of hydraulic actuating elements, and to realize high-precision action control in the automated production process.
Construction machinery: in excavators, loaders, cranes and other construction machinery, used to control the action of hydraulic cylinders and hydraulic motors, to realize a variety of complex actions and operational functions of construction machinery, improve the efficiency and operational performance of construction machinery.
Metallurgical industry: in the metallurgical production of continuous casting, steel rolling and other processes, used to control the direction and flow of oil in the hydraulic system, to achieve precise control and regulation of metallurgical equipment, to ensure the smooth progress of metallurgical production and product quality.
Shipbuilding: It is used to control the movement of hydraulic actuating elements in hydraulic equipment such as rudder system, anchor system, cargo lifter system, etc. to realize the operation of sailing, berthing, cargo loading and unloading of the ship, and to improve the maneuvering performance and safety of the ship.

Advantages:

Precise control: it can precisely control the pressure, flow or direction of the oil flow according to the input electric signal, realizing high-precision control of the hydraulic system and meeting various complex control requirements.
Remote control: the electrical signal is easy to transmit, and it is simple to realize remote control, which is convenient for centralized control and management of the hydraulic system.
Reduction of impact: it can continuously and proportionally control the pressure and flow of the hydraulic system, realize the control of the position, speed and force of the actuator, and reduce the impact of the pressure change, improve the stability and reliability of the system.
Simplified system: It reduces the number of components, simplifies the oil circuit, reduces the complexity and cost of the system, and also improves the reliability and maintenance of the system.
Flexible Configuration: With a variety of control methods and functional options, such as electromagnetic, electric, electro-hydraulic, etc., it can be flexibly configured and selected according to different application requirements.
