Solenoid valves are divided into direct-acting and pilot-operated types.They are mainly used in central air conditioners, heat pumps, ice-making machines, ice-cream machines, refrigerating systems and dehumidifiers, and automatically open or close the internal passage of the valve. 

Features

1. Low power consumption, good reliability, good opening performance, and large maximum working pressure difference

2.Advanced technological process, built-in welding silver ring, melting silver wire from inside to outside, to ensure no leakage phenomenon.

3.The ultra-low temperature is minus 40 degrees, and the working performance is good.

4. When the low voltage is 187 volts, the valve opening ability is strong.

5.The internal leakage is less than 99ml/min. (The national standard is 300ml/min).

6.The head, steel ball and core iron materials used by our company are stainless steel made in Japan.The guaranteed life is more than 200,000 times. (The national standard is 100,000 times) 

7.The company's products use imported stainless steel raw materials, and are produced and processed by Japanese Kitamura machine tools and Panasonic welding machines. Guaranteed quality 100% pass rate. 

8.The sealing parts in the valve body contains steel balls in contact with copper to form a hard seal, so that the product has good sealing performance, refrigerant corrosion resistance, high temperature resistance of 180 °C, and long service life.
