Key Products Showcase
1.Solenoid Valve Series
These solenoid valves include direct-acting and pilot-operated types, designed for reliable flow control in a wide range of HVAC&R applications.
They are widely applied in central air conditioning, heat pumps, ice-making equipment, ice cream machines, refrigeration and cold storage systems, dehumidification/humidification equipment, and water systems, enabling automatic opening and closing of internal flow channels for efficient system operation.
2.Drain Pump Series
Designed for floor-standing and ceiling-mounted air conditioning indoor units, this product efficiently removes condensate water produced by the heat exchanger during cooling and dehumidification processes, helping maintain stable system performance and improve user comfort.
3.Pressure Controller
This pressure controller is widely used for high- and low-pressure protection in HVAC&R systems, including residential and commercial air conditioning, automotive air conditioning, ice-making equipment, air and water pressure systems, and refrigeration and cold storage applications.
By providing reliable pressure monitoring and protection, it helps enhance system safety, efficiency, and operational stability.
4.Needle Valve (Charging Valve) Series
Charging valves are widely used in air conditioning and refrigeration systems, installed on liquid and suction pipelines. As essential service components, they provide easy access for vacuuming, refrigerant charging, and system maintenance, helping ensure efficient servicing and stable HVAC&R system performance.
