Solenoid Valves are simple electrically
operated devices. The valve plug is held in place by a spring. When
electric power is applied to the solenoid (Energized), the current draw
through the coil generates an electromagnetic force which opposes the
spring, causing the plug to change position. When power is taken away
(De-energized), the spring returns the plug to the normal position.
Solenoid valves are ideal for fluid shutoff and switching in general
service applications. Proportional solenoid control valves are available
for modulating service.
