2SO030-040 Series: 2/2 Direct Acting Normally Open Valve
The 2SO040 series normally open solenoid valve is direct acting, it does not require a minimum operating differential pressure. As shown in the diagram below, when the coil is energized, it pushes the solenoid plunger downward to close the main valve orifice and closes the valve. When the coil is de-energized, the spring forces the plunger upward to open the valve main orifice and opens the valve.

ALL standard valves are supplied with Continuous Duty Coils of the proper class of insulation for the service indicated on the valve. It is normal for the coil temperature may become hot after being energized for extended periods. Smoke or burning odor indicates excessive coil temperature and the power should be disconnected to the coil immediately.

SERVICE LIFE: The service life of the solenoid valve depends on the operating conditions such as pressure, temperature, type of medium, and the voltage. Normally the STC solenoid valves are reliable for more than 5 million cycles.
