PR 2224 Valve Controller

Description

Take control of your hydraulic or pneumatic proportional valves with the 2224 Valve Controller, from PR electronics. Designed to regulate single- or double-coil valves, it delivers precise oil or air flow via programmable inputs in mA, V, or potentiometer signals. Smooth ramp-up/down, jump-through start, and adjustable deadband eliminate jerky motion and valve lag. A three-digit LED displays valve output as a percentage, while password-protected parameters safeguard settings. With pulse output to prevent valve sticking and optional PWM up to 400 Hz, the 2224 ensures responsive, accurate, and reliable performance—ideal for machine control, joystick movement, and process regulation.

• multifunction user interface consisting of three push buttons and a 3-digit LED display
• all parameters are protected against unauthorized changes with a password

Common Applications for a Valve Controller

• control and regulation of single- or double-coil hydraulic and pneumatic proportional valves
• for accurate oil flow regulation, linear soft acceleration and deceleration, modulated output signal, and programmable deadband
• highly suitable for joystick regulation of A/B movements
• where changes to A and B need direct selection or according to the value of an input signal

Technical Characteristics

The 2224 Valve Controller is a versatile, DIN-rail mounted device designed for precise control as well as monitoring of modulating control valves in industrial automation systems. It enables accurate positioning of valve actuators using analog input signals (for example, 4-20 mA) and also provides feedback on valve position, ensuring optimal process control. Commonly used in chemical processing, water treatment, in addition to HVAC systems, the 2224 enhances process efficiency, safety, and reliability. This valve controller, from PR electronics, flexible configuration options support both linear and rotary valve types. With built-in diagnostics and signal conversion capabilities, it also aids in system troubleshooting and performance monitoring, reducing downtime and maintenance costs.

• during operation, the display shows the present output signal as a % of the I valve
• programmable current or voltage input for standard signals according to order schedule, joystick / potentiometer, or a special non-programmable input
• digital inputs for external control functions
• pulsating current output prevents the valve from sticking
• optional programming of the modulation frequency (PWM) between 8 and 400 Hz
• multiple adjustable parameters such as output currents, ramp times, jump values, chopper frequency, reversal, deadband, and ON/OFF functions
• mounting for a standard 11-pole socket which can adapt for DIN rail or plate use with PR’s 7023 adaptor and 7024 mounting keying
