The refrigeration solenoid valve is a direct-acting solenoid valve, which is mainly used in central air conditioners, heat pumps, ice machines, ice cream machines, refrigeration and refrigeration systems, and dehumidifiers to automatically open or close the internal passage of the valve.

Features

• The refrigeration solenoid valve has low power consumption, good reliability, excellent opening performance, and a large maximum working pressure difference, which can ensure the efficient and stable operation of the refrigeration system.
• Direct-acting solenoid valve adopts advanced technology, with a built-in silver welding ring, and the silver wire is melted from the inside to the outside to ensure no external leakage.
• It can still work normally in an ultra-low temperature environment, and its performance is stable at minus 40℃, which is suitable for application requirements under extremely cold conditions.
• Even at a low voltage of 187V, the solenoid valve can still provide strong valve opening capacity.
• The internal leakage of the solenoid valve is less than 99ml/min, which improves the energy efficiency of the system.
• The service life of the solenoid valve exceeds 200,000 times, which ensures the long-term stable operation of the equipment and reduces the cost of maintenance and replacement.

Tips: Comparison between direct-acting solenoid valves and pilot-operated solenoid valves

Direct Acting Solenoid Valves operate by using electromagnetic force to directly move the valve spool, without relying on system pressure. They are ideal for low-pressure differential and small flow applications, featuring simple construction and fast response times. These valves are suitable for small devices and low-pressure refrigeration systems, but their flow capacity is limited, and they consume more power.

Pilot Operated Solenoid Valves, on the other hand, control a pilot valve using electromagnetic force, which in turn operates the main valve. These valves depend on system pressure to function and are designed for large flow rates and high-pressure differential applications. They are more energy-efficient than direct acting valves and are commonly used in large refrigeration systems and industrial applications. However, their response time is slower, and their structure is more complex, requiring sufficient system pressure to operate.
