Supplied with full traceability and documentation.... Price & Availability Contact us for pricing / 询价 It belongs to the 4WRPEH series, which is characterized by its direct-operated, spool-type design with integrated electronic proportional solenoid. This valve is a 4/3-way version with a nominal size of NG6 (CETOP 03) and is capable of handling flow rates up to 12 L/min at a pressure drop of 10 bar per control edge. The valve operates with a 24V DC supply and includes an integrated amplifier (OBE) for simplified wiring and enhanced control dynamics. Manufactured by Hengli, a leading Chinese hydraulic component manufacturer, this valve is designed to meet or exceed the performance of comparable models from Bosch Rexroth (e.g., 4WRPEH6C4B12L-31/M/24A1 is a direct equivalent). The valve features a robust cast iron body, hardened and ground spool, and low hysteresis, ensuring accurate repeatability. The integrated electronics provide a command input of 0-10V or 4-20mA, making it compatible with various industrial control systems. The valve is suitable for applications requiring precise velocity or position control, such as machine tools, injection molding machines, and test rigs. The 4WRPEH6C4B12L-31/M/24A1 is supplied as a new, original spare part with a 12-month warranty. It is a direct replacement for the Bosch Rexroth model 4WRPEH6C4B12L-31/M/24A1, offering identical mounting dimensions and performance characteristics. With its high dynamic response and reliable operation, this valve is an excellent choice for upgrading or maintaining hydraulic systems in industrial automation environments. The Hengli 4WRPEH6C4B12L-31/M/24A1 is a high-performance proportional directional valve designed for precise control of flow and direction in hydraulic systems. Basic Product Information Size NG6 (CETOP 03) with 4/3-way spool design Nominal flow up to 12 L/min at 10 bar per control edge 24V DC supply with command input 0-10V or 4-20mA Low hysteresis and high repeatability for precise control Hardened and ground spool for long service life Interchangeable with Bosch Rexroth 4WRPEH6 series Direct-operated proportional directional valve with integrated electronics (OBE) Technical Specifications Version & Model Difference The 4WRPEH6C4B12L-31/M/24A1 is part of the Hengli 4WRPEH6 series, which is a direct equivalent to the Bosch Rexroth 4WRPEH6 series. The '31' in the model number indicates the series revision (comparable to Rexroth series 31). The 'M' denotes the spool type with a specific metering characteristic, and '24A1' refers to the 24V DC supply with integrated electronics (OBE) and command input 0-10V/4-20mA. Compared to older versions (e.g., series 20), series 31 offers improved dynamic response and reduced power consumption. The valve is also available with different spool symbols (e.g., C4, C5, C6) to suit various flow control requirements. Application Scenarios Can I use this valve with a 12V DC supply? No, the valve is designed for 24V DC supply (20.4-26.4V). Using a lower voltage will result in insufficient solenoid force and improper valve operation. For 12V systems, you would need a different model with a 12V coil. What type of command signal does the integrated electronics accept? The integrated electronics (OBE) accepts either a 0-10V voltage signal or a 4-20mA current signal. The input can be selected via a DIP switch on the electronics. The valve is factory-set to 0-10V but can be changed by the user. Is the valve suitable for use with water-glycol or other fire-resistant fluids? The standard valve is designed for mineral oil based hydraulic fluids. For use with fire-resistant fluids (e.g., HFC, HFD), special seals are required. Please contact our sales team for a version with FKM seals or other options. What is the difference between the Hengli 4WRPEH6C4B12L-31/M/24A1 and the Bosch Rexroth equivalent? The Hengli valve is a direct equivalent to the Bosch Rexroth 4WRPEH6C4B12L-31/M/24A1. It has the same mounting dimensions, performance characteristics, and electrical connections. The main difference is the brand and price; Hengli offers a cost-effective alternative without compromising on quality. Hengli 4WRPEH6C4B40L-20/G24K0/A1M Proportional Directional Valve
