[MATERIAL]: The product is mainly made of cast copper with copper coil, which improves the strength and applicability of the valve.
[SIZE]: 102mm*62mm (4.016" * 2.44"), thread diameter: 20mm (0.787"), interface pipe diameter: 1 / 2" NPT thread, flow diameter: 16mm (0.63").
[N/C]: The solenoid valve is normally closed, which means it is closed when the power is not supplied, which effectively ensures the safety of use..
[WIDE APPLICATION]: Applicable temperature: - 5 ℃ ~ 80 ℃,Working pressure: water, air: 0 ~ 7kgf/cm2, oil: 0 ~ 5kgf/cm2,Working environment: air, water, oil and gas.
[MATTERS NEEDING ATTENTION]: Amps power required by adaptor: at least 1.2A. As the product is normally closed solenoid valve, the working time shall not be too long, and the working time is recommended to be less than half an hour. If more than half an hour will begin to appear heating state, after the solenoid valve heating, try to let it rest for half an hour before working..
