4WRA6E30-2X/G24K4/V is a proportional directional control valve of Rexroth. Its core function is to realize stepless regulation of the direction and flow of hydraulic oil through electrical signals, and it has closed-loop control performance based on position feedback, which can accurately control the action of executive components (such as oil cylinders, motors). The model "G24K4/V" indicates that it adopts 24V DC power supply, is equipped with a proportional amplifier with diagnostic function, and has a vibration-resistant design, which is suitable for industrial scenes with frequent load changes.

2FRE10-4X/25LBK4V is a proportional flow control valve with two-way function. It mainly relies on temperature compensation and pressure compensation to control the flow according to the electrical control value, ensuring stable flow output not affected by system pressure and oil temperature changes. The "25LB" in the model means that its maximum adjustable flow is related to the 25L specification, and it has a built-in one-way valve to allow oil to flow back freely from port B to port A, which is often used in speed control links of hydraulic systems.

• 4WRA6E30-2X/G24K4/V: The maximum working pressure is 315 bar, the rated flow rate matches the 30 specification (specific value refers to the product manual), the control signal is 4~20mA or 0~10V, the power supply voltage is DC 24V±5%, and the coil resistance is generally 10~30Ω (subject to the actual model).
• 2FRE10-4X/25LBK4V: The maximum working pressure is 350 bar, the recommended oil temperature range is -20℃~80℃, the flow control range is matched with the 25 specification, the control signal is consistent with the proportional directional valve, and the oil cleanliness requirement is NAS 8 level or higher.

Each code segment has a clear definition: 4W represents a 4-way valve; RA means proportional directional control valve with position feedback; 6 is the structural size code; E indicates the direction of the oil port; 30 is the flow specification code; 2X represents the design series; G24 means DC 24V power supply; K4 indicates the integrated proportional amplifier with diagnostic function; V represents the vibration-resistant design to adapt to harsh working environments.
