Normally Closed Solenoid Valves – Energize to Open: Reliable Performance for Severe Service Applications
In industrial environments where handling aggressive chemicals, caustics, and ultrapure liquids is critical, the reliability of solenoid valves becomes paramount. The Normally Closed Solenoid Valves – Energize to Open from Plast-O-Matic are engineered to meet the rigorous demands of severe service applications, offering unparalleled performance and longevity. With a design that ensures secure and efficient operation, these valves are a trusted solution for a wide range of industrial processes.
Understanding Solenoid Valves
Solenoid valves are electromechanically operated devices that control the flow of liquids or gases in various industrial applications. These valves are activated by an electric current, which energizes a solenoid coil, causing the valve to open or close. Normally closed solenoid valves remain in a closed position when de-energized and open only when energized. This design is particularly useful in applications where it is essential to maintain a closed state during power loss, ensuring that potentially hazardous or critical processes remain secure.
