TECHNO 3/8 Inch 2/2 Way Direct Acting Solenoid Valve, 2W-040-10

A TECHNO 3/8 Inch 2/2 Way Direct Acting Solenoid Valve 2W-040-10 is a type of valve that uses electrical energy to control the flow of fluids such as water, air, gas, or oil. Unlike pilot-operated solenoid valves, which require an external source of pressure to actuate the valve, direct-acting solenoid valves operate directly through the force generated by the solenoid coil.

These valves consist of a solenoid coil, a plunger or armature, and a sealing element such as a diaphragm or piston. When the solenoid coil is energized, it creates a magnetic field that moves the plunger or armature, opening or closing the valve. This action allows or blocks the flow of fluid through the valve.

Direct-acting solenoid valves are available in various configurations, including normally closed (NC) and normally open (NO). In a normally closed valve, the valve is closed when de-energized, and it opens when the solenoid is energized. Conversely, in a normally open valve, the valve is open when de-energized, and it closes when the solenoid is energized.

These valves are widely used in applications where rapid response and precise control of fluid flow are required. They are commonly found in industries such as HVAC, refrigeration, automotive, medical equipment, and process automation.

Direct-acting solenoid valves offer advantages such as quick response times, simple operation, and reliability. However, they may have limitations in terms of maximum flow rate and pressure compared to pilot-operated solenoid valves. Proper selection and sizing of the valve are crucial to ensure optimal performance and efficiency in the intended application.
