UW-40 2W400-40 1-1/2'' 2/2 Way NC Semi Diaphragm Flow Control Valve
The 2W400-40 solenoid valve is brass valves two-way, semi-direct lift valve that operates in a normally closed position.This means that there are two ports in which the medium flows and the valve will open to allow the medium to pass when the coil is energized. 2 / 2 Way G1-1/2 Inch Normal Close Type Operated Brass Solenoid Valve 2W400-40.High quality electric solenoid valve, for water, air or oil. It's applicable in many fields.
2W400-40
2W: 2 Positon 2 Way Solenoid Valve. Solenoid valve has 2 pipe connections, an inlet called the cavity port and an outlet called the body orifice port. When the valve is energized the plunger opens allowing media to flow through the valve in the cavity port and out the body orifice port.Turn off the power. The orifice closes and flow through the valve stops.
400: The Aperture of Flow Rate is 40 mm
40:Joint Pipe Bore is G1-1/2 Inch Female Thread
