A Proportional Valve Card is an electronic circuit designed to precisely control proportional hydraulic or pneumatic valves. This card provides the necessary electrical current to activate the valve solenoids and adjusts their operation based on the input control signal.
How It Works
The proportional card processes the control signal (e.g., voltage or current) and converts it into a proportional electrical output. This output signal regulates the position or function of the proportional valve, enabling precise control of fluid flow or pressure in the system.
Main Components
- Control Signal Input: Receives signals from controllers or PLCs.
- Amplifier Unit: Amplifies the input signal and sends it to the solenoids.
- Feedback Circuit: Monitors the valve operation and applies necessary adjustments.
- Manual Adjustments: Includes knobs or switches for manually setting parameters.
Features and Advantages
- Precise Control: Ensures accurate flow and pressure regulation.
- Fast Response: Suitable for sensitive industrial applications.
- Adjustability: Configurable for various proportional valve types.
- High Stability and Efficiency: Provides consistent and reliable performance.
Applications
Proportional valve cards are used in advanced hydraulic and pneumatic systems, particularly in industries such as automotive, industrial machinery, robotics, and automated production lines.
