Description:

Rexroth Proportional Valve 4WRKE25W8-350L-35/6EG24EK31/A1D3M is a high-performance proportional directional valve for industrial hydraulics manufactured by Bosch Rexroth. It is a pilot-operated two-stage proportional directional valve with electrical position feedback and integrated electronic control. The valve controls the pilot stage by means of a proportional solenoid, which in turn realizes the position adjustment of the main control slide valve, thus accurately controlling the flow direction and size of the hydraulic fluid. Max. 350 bar. proportional to the opening of the main control slide valve. 24 V DC with 7-pole circular connector (6+PE) according to DIN EN 175301-804. Controlled by means of electrical signals, with analog signal input, command value range ±10 V. Approx. 17.92 kg.

Areas of application :

Machinery manufacturing: in various heavy machinery, machine tools and other equipment, used to control the direction and speed of the movement of hydraulic cylinders or hydraulic motors, to achieve precise processing and operation.
Automated production lines: In automated production lines, to control the movement of robot joints, hydraulic systems of material handling equipment, etc., to ensure the efficiency and precision of the production process.
Construction machinery: In the hydraulic systems of construction machinery such as excavators and loaders, the expansion and contraction of hydraulic cylinders and the rotation of hydraulic motors are controlled to realize the functions of digging, loading and lifting of the equipment.
Plastic molding machinery: in the injection molding machine, extruder and other equipment, control the opening and closing of the mold, material flow, etc., to ensure the stability of the molding process and product quality.
Metallurgical industry: used in the hydraulic system of rolling mill, continuous casting machine and other equipments, to control the lifting, moving and pressure adjustment of rolls, to ensure the quality and efficiency of metal processing.
Shipbuilding: in the ship's rudder system, lifting device and other hydraulic systems, to realize the ship's steering, lifting and other functions.

Advantages:

Precise control: This proportional valve is able to monitor the position of the main control slide valve in real time through the internal inductive position sensor and feed it back to the control electronics. The control electronics will automatically adjust the current of the proportional solenoid according to the deviation between the set value and the actual value, so as to precisely control the position of the main control slide valve. This closed-loop control allows the flow and direction of the hydraulic fluid to be precisely controlled, which ensures the stability and precision of the system even under complex working conditions.
Fast Response: Due to the use of pilot-type two-stage control structure, the pilot stage can quickly respond to changes in electrical signals and quickly transfer them to the main control slide valve to realize fast flow and direction switching. This enables the hydraulic system to perform efficiently in situations that require fast action, such as robot joint control on automated production lines.
High reliability: Bosch Rexroth, a globally recognized manufacturer of hydraulic equipment, produces proportional valves that are designed and manufactured using strict quality control standards. The valve's compact structure and parts are precision-machined and rigorously inspected to withstand long-term work at high pressure and high flow rate. Meanwhile, its proportional solenoid adopts a sealed design, which can effectively prevent oil contamination and leakage and improve the reliability and service life of the valve.
Integrated electronic control: The proportional valve integrates an electronic control device, making the control more intelligent. By adjusting the valve and the electronic device, the deviation of the equipment in mass production can be reduced. This integrated design not only simplifies the installation and commissioning process of the system, but also improves the overall performance and stability of the system.
Strong adaptability: The proportional valve is suitable for a wide range of hydraulic oil types, such as HL, HLP, HLPD, HVLP, HVLPD, HFC and so on. Meanwhile, it has a wide working pressure range of up to 350 bar, which can meet the pressure requirements of hydraulic systems in different industrial fields. In addition, its flexible electrical connection with standard 24 V DC power supply and analog signal input facilitates integration with various control systems.
Easy maintenance: The structure of this proportional valve has been designed with ease of maintenance in mind. The coil of its proportional solenoid is removable and can be operated quickly when it needs to be replaced or repaired. At the same time, key components such as its main control slide valve and pilot stage are also easy to disassemble and clean
