Digital valve controller XV1-M

Power 24VAC/DC Unipolar Type Expansion Valve 2-Coil Method, 1~2-Coil Method EEV Valve Superheat and Hot Gas Bypass Temperature Control 4~20mA External Input EEV Drive mode Modbus RTU Communication The Electronic Expansion Valve (EEV) Controller is a precision control device designed to regulate refrigerant flow in refrigeration and air conditioning systems. By continuously monitoring system conditions through sensors and adjusting the valve opening, the controller optimizes refrigerant flow, enhancing energy efficiency and system performance. 1. Precise Refrigerant Flow Control: Maintains consistent superheat levels by regulating refrigerant flow through the evaporator. 2. Sensor-Based Intelligent Control: Adjusts valve openings using real-time superheat data obtained from suction gas temperature and pressure sensors. 3. Automatic PID-Based Adjustment: Utilizes an advanced PID control algorithm to automatically regulate refrigerant flow based on system conditions, ensuring stable and efficient operation. 4. Comprehensive System Protection: Provides shutdown alerts and warning alarms in the event of overheating, high pressure, or refrigerant shortages, safeguarding the system. 5. Durability for Industrial Use: Engineered for stable and reliable operation even under harsh industrial conditions. 6. Multiple Control Modes: Supports various control applications, including Superheat control, Hot gas bypass temperature control, Drive control for step motors or pulse motors.
