The GV45-4-AT proportional solenoids, an electro-mechanical converting device, can be applied on Rexroth proportional flow control valve and proportional directional control valve in DC 24V electro-hydraulic proportional control system used together with the proportional directional control amplifier. Within the scope of the rated stroke and the rated current, the output force is proportional to the input signal. With certain preset electric current, the counter force of its compressing spring can be adjusted to change the output flow of the proportional flow valve. The infinitely variable control of the input current within the rated range can realize the continuously viable, reversing and remote control of the actuator of the hydraulic system in the rated range.
