Introduction to Normally Open Solenoid Valves
Normally open solenoid valves are a type of valve that remains open in its default state. When an electrical current is applied to the solenoid coil, the valve closes. These valves are widely used in various industries such as water treatment, HVAC (Heating, Ventilation, and Air Conditioning), automotive, and industrial automation. They play a crucial role in controlling the flow of fluids, including gases, liquids, and steam. The normally open design is beneficial in applications where the system requires continuous flow under normal conditions and the ability to shut off the flow when necessary.
