ADF Compact Plug-Mounted Proportional Valve Amplifier

Product Overview

ADF Compact Plug-Mounted Proportional Valve Amplifier is a dedicated electronic drive unit for proportional Hydraulic valve. It receives control command signals and converts them into stable driving current to actuate proportional solenoids, realizing precise regulation of pressure, flow or direction in the hydraulic system. Featuring plug-mounted compact design, this amplifier can be directly plugged onto the coil of proportional valve, saving cabinet wiring space and simplifying installation on various Machine hydraulic control loops. It supports signal adjustment, gain and offset tuning for matching different proportional valves.

Technical Specifications

- Mounting type: Plug-mounted, directly fit on proportional valve solenoid coil

- Power supply: 24V DC

- Input signal options: 0-10V / 4-20mA

- Output: Adjustable driving current for proportional solenoid

- Built-in functions: Gain adjustment, offset calibration, fault indication, dither signal

- Working temperature: -20℃ ~ +60℃

- Protection class: IP65

- Housing: Compact plastic casing, shock and vibration resistant

- Compatibility: Matches most common proportional Hydraulic valve models

Working Principle

This amplifier collects the setpoint signal from the controller. After internal signal processing, gain and offset correction, it outputs modulated current to the proportional solenoid of the Hydraulic valve. The built-in dither signal reduces valve spool friction, improving response and control linearity. The amplifier feeds the control signal to adjust the valve opening, so the hydraulic system can accurately output target pressure or flow. Installed directly on the valve, it avoids signal attenuation during long-distance wiring and ensures stable control performance of the Machine.

Core Advantages

1. Plug & play compact structure, direct installation on proportional valve, less wiring work

2. Integrated dither function, reduces spool static friction, enhances control accuracy

3. Adjustable gain and offset parameters, flexible to match different Hydraulic valve

4. Good anti-interference ability, stable operation in complex hydraulic system environment

5. IP65 protection, suitable for workshop and industrial Machine on-site harsh conditions

Application Range

Used together with proportional Hydraulic valve for hydraulic system of multiple Machine: injection molding machine, hydraulic press, metal forming equipment, hydraulic test bench, metallurgical machinery, automation production line, construction machinery hydraulic control unit.
