Understanding Normally Closed Solenoid Valves
What are Normally Closed Solenoid Valves?
Normally Closed (NC) solenoid valves are designed to maintain a closed position when not energized. This means that the flow of fluid is blocked until the valve is activated by an electrical signal. This functionality is critical in applications involving hazardous or volatile fluids, such as ammonia, where accidental leaks must be prevented.
How Do They Work?
When an electrical current passes through the solenoid coil, it generates a magnetic field that pulls the valve’s plunger, opening the path for fluid flow. Once the electrical signal is removed, a spring mechanism returns the plunger to its original position, closing the valve and stopping the flow. This simple yet effective mechanism ensures that the valve operates reliably across various industrial settings.
Applications of Normally Closed Solenoid Valves
Industrial Applications
These valves are widely used in industrial environments:
- Chemical Processing: They control the flow of corrosive chemicals, ensuring safety and efficiency.
- Refrigeration Systems: In ammonia refrigeration systems, NC solenoid valves are crucial for managing refrigerant flow and maintaining optimal pressure levels.
