Rexroth A4VG series proportional valves are used in load sensing hydraulic systems for precision flow control. They operate by proportionally controlling the hydraulic fluid flow between an inlet port and an outlet port. These valves are suitable for industrial applications that require smooth and accurate flow control.
Rexroth A4vg Pump Serie 32
The A4VG32 is a 32 mm port size proportional valve suitable for flows up to 50 lpm. It has a compact package size and provides high flow capacity, making it ideal for applications that require high power and a small footprint. The A4VG32 features a closed-loop control spool for smooth and stable control, providing precise hydraulic fluid flow control at low speeds. It uses a solenoid actuator for valve control and offers a maximum operating pressure of 315 sbarra.
Rexroth A4vg Pump Series 40
The A4VG40 is Rexroth’s high-flow 40 mm port size proportional valve. It can handle flows up to 150 lpm, making it suitable for applications requiring high power and force. Like the A4VG32, the A4VG40 uses a closed-loop controlled spool to provide smooth and precise control of hydraulic fluid flow. This series is especially useful for proportional applications involving large hydraulic cylinders and heavy-duty actuators that need accurate position or motion control.
Applications That Commonly Use Rexroth A4VG Series Valves
