Description:

Rexroth Proportional Valve 4WRKE25W8-220L-33/6EG24EK31/C1D3V is a high performance industrial hydraulic proportional directional valve. It is pilot operated and controlled by a proportional solenoid. The main components of the valve include a pilot operated control valve, a main spool, an inductive position sensor and an integrated electronic control unit. The valve's control edge geometry is optimized for use as a pilot control valve. Its proportional solenoid is a pressure-sealed, wet-pin DC magnet with a removable coil.

Areas of application:

Industrial automation: In automated production lines, it is used to accurately control the direction and speed of the movement of hydraulic cylinders or hydraulic motors to realize the control of complex mechanical movements, such as the motion control of robotic joints, the hydraulic drive of material handling equipment on automated assembly lines, and so on.
Machinery Manufacturing: In a variety of mechanical processing equipment, such as presses, injection molding machines, etc., used to control the opening and closing of molds, material molding pressure and speed, etc., to improve production efficiency and product quality.
Plastic and Rubber Processing: In plastic and rubber molding equipment, it is used to control the hydraulic system to ensure the stability and accuracy of the molding process, such as plastic injection molding machines, rubber vulcanizing machines and so on.
Food and Pharmaceutical Industry: In food and pharmaceutical equipment, used to control the operation of hydraulically driven agitators, conveyor belts and other equipment to ensure hygiene and precise control of the production process.
Building materials industry: in building materials production equipment, such as concrete mixers, brick molding machines, etc., used to control the pressure and flow of the hydraulic system, to ensure the stability of the production process and product quality.
Surface treatment: In surface treatment equipment, such as electroplating and spraying equipment, it is used to control the operation of the hydraulic system to ensure the uniformity and quality of the surface treatment process.

Advantages:

Precise control: The proportional solenoid and the integrated electronic control unit enable precise control of the direction and flow of the oil flow. This precise control enables the hydraulic system to respond more accurately to the control signals, improving the response speed and control accuracy of the system.
High Reliability: The valve is pilot operated and the main spool position is maintained by a center spring, which keeps it in the central position even in the absence of an input signal. This design improves the reliability and stability of the valve and reduces system failures due to external interference or loss of signal.
Integrated electronic control: The valve has a built-in integrated electronic control unit (OBE) that enables real-time monitoring and feedback control of the spool position. This integrated electronic control not only improves control accuracy, but also simplifies system design and reduces the need for external control components.
Adaptable: Suitable for use with a wide range of hydraulic fluids, including mineral oils, water-containing flame-retardant hydraulic fluids and phosphate ester hydraulic fluids. This wide range of applicability allows the valve to be used in a variety of industrial environments to meet the needs of different users.
High flow capacity: with a maximum flow rate of up to 3,000 liters per minute, the valve is able to meet the demands of high-flow hydraulic systems and is suitable for use in a variety of large industrial equipment and complex application scenarios.
Easy to install and maintain: Adopting sub plate mounting method, it conforms to the interface mode of ISO 4401, which is easy and quick to install. At the same time, the valve has a simple structural design, easy to maintain and repair, reducing the user's cost of use.
Long life: During the design and manufacturing process, high quality materials and advanced manufacturing technology are used to ensure the long life and high reliability of the valve. This not only reduces the frequency of replacement, but also reduces the user's maintenance costs and downtime.
