ASCO S261SH02N3DG5 1/2 Inch Nc 120V 0/30#Shutoff Valve
The ASCO S261SH02N3DG5 is a 1/2-inch normally closed (NC) solenoid shut-off valve intended for use in a variety of industrial applications, including HVAC systems. It is a control mechanism that opens and closes in response to an electrical signal to control the flow of gases or liquids. A solenoid coil inside the valve functions similarly to an electromagnet. The coil produces a magnetic field when it is powered by a 120-volt AC signal. A plunger is drawn in by the activated coil's magnetic field, which opens a valve's internal passageway and permits gas or liquid to pass through. On the other hand, the valve's spring shuts the passage and stops the flow when it is de-energized. The valve on this particular model is typically closed.
