Four Core Products
Product application：
Solenoid valves are divided into direct-acting and pilot-operated, mainly used in central air-conditioning units, heat pumps, ice machines, ice cream machines and freezing and refrigeration systems and humidifier/ dehumidifier used to automatically open or close the valve's internal access.
Character：
Low power consumption, good reliability, good opening performance, maximum working differential pressure.
Advanced process, built-in soldered silver ring, melted silver wire from inside to outside, ensuring no leakage.
Ultra-low temperature of minus 40 degrees, good working performance.
Strong valve opening ability at low voltage 187 volts.
Internal leakage: FDF2A-4A less than 30ml/min; FDF6A less than 50ml/min.
The company produces and uses the head, ball, core iron material for the Japanese assets soft magnetic stainless steel. Guaranteed life of more than 200,000 times (the national standard is 100,000 times).
The company's products use part of the imported materials, through the Japanese Kitamura machine tools and Panasonic welding machine to production and processing, to ensure that the quality of 100% pass rate.
Product application：
It is used in the indoor unit of cabinet air-conditioners and ceiling air-conditioners to hold the condensate produced by the heat exchanger during refrigeration and dehumidification.
Product application：
The charging valve is mainly installed in the liquid pipe or suction line in the air-conditioning and refrigeration series, and is used as a service valve for evacuating vacuum and adding refrigerant during maintenance.
Character：
Simple structure, easy to use.
Prevent refrigerant leakage by cooperating with the valve nozzle during use.
