The 2W400-40 is normally closed diaphragm solenoid valve which possess a simplistic structure, minimal fluid resistance, and superior flow capacity compared to other valve types of the same specifications. It is achieved through the movement of diaphragms that effectively prevent stem leakage. These valves are suitable for applications involving media containing hard suspended solids and particularly well-suited for corrosive, viscous and slurry media.
Brass valve body
The body of 2W400-40 is made of solid brass and has a thick wall for longer service life. The smooth thread of fine machining ensures continuous operation is not easily damged, making it safer and more reliable.
Stable Solenoid coil
The stable coil enables good heat dissipation, good insulation performance. This coil will not burn out easily during operation. Clearly and comprehensively display the specific parameters of the water valve.
Wide application
Industrial usage, household usage, can be used for air control, liquid control, irrigation control.
Pay Attention:
◆ Please check whether the product is intact before use
◆ Please confirm that the installation conditions are in accordance with the specifications
◆ Please use in a stable environment
◆ Pay attention to clean up dust and other things that affect operation
