REXROTH Proportional Directional Valve 2-Position 4-Way

The 2-position and 3-position 4-way Rexroth proportional directional valves are direct-acting, plate-type valves; operated by a proportional solenoid with a center thread, the coil of which can be disassembled separately. The solenoid can be controlled by an external amplifier (WRE type) or a built-in amplifier (WREE type).

Example Model: 4WREE10E75-2X/G24K31/A1V

4WRE → Direct-acting proportional directional valve, plate-type valve

E → With built-in amplifier (if E is not available, an external amplifier can be connected)

10 → 10-way valve (also available in 6-way, etc.)

E → Functional symbol (also E1-, V, W, W1-, EA, WA, etc.)

75 → Rated flow rate (NS10) at a differential pressure of 10 bar: 75 L/min (Also available: (NS6)08, 16, 32; (NS10)25, 50, 75, etc.)

2X → 20 to 29 series (20 to 29: installation and connection dimensions unchanged)

G24 → 24V DC power supply

K31 → With socket conforming to E DIN 43 563-AM6-3, without plug. Plug must be ordered separately. (K4 refers to socket conforming to DIN 43 650-AM2, without plug)

A1 → WREE type A1 or F1 interface: setpoint input ±10 V (F1 = setpoint, input 4 to 20mA)

V → Fluororubber rectangular seal. Hydraulic oil conforming to DIN 51 524 standard (HL, HLP)

Differences between Servo Valves and Proportional Valves

REXROTH

There are no strict rules regarding the differences between servo valves and proportional valves. Because the performance of proportional valves has improved, they are gradually approaching that of servo valves, leading to the emergence of proportional servo valves in recent years.

REXROTH

The main differences between proportional valves and servo valves are as follows:

1. Different drive devices. The drive device for proportional valves is a proportional solenoid; the drive device for servo valves is a force motor or torque motor;

2. Different performance parameters. 2.1 Servo valves have no dead zone in the neutral position, while proportional valves do. Therefore, their applications differ. Servo valves and servo proportional valves are mainly used in closed-loop control systems, while other proportional valve structures are mainly used in open-loop control systems and closed-loop speed control systems.

2.2 Servo valves have a higher frequency response (response frequency), reaching up to around 200Hz, while proportional valves generally have a maximum frequency of tens of Hz.

2.3 Servo valves have higher requirements for hydraulic fluid, requiring filtration to prevent clogging, while proportional valves have lower requirements.

3. Valve core structure and machining precision differ. Proportional valves use a valve core + valve body structure, with the valve body also serving as the valve sleeve. Servo valves and servo proportional valves use a valve core + valve sleeve structure.

4. Neutral position functions differ. Proportional directional valves have neutral position functions similar to ordinary directional valves, while servo valves only have an O-type neutral position function (E-type for Rexroth products).

5. Rated pressure drop differs.

Proportional servo valves offer performance between servo valves and proportional valves.

Directional control valves are a type of proportional valve used to control flow rate and direction.
