Normally Closed Solenoid Valves are available in two different pipe sizes, 1/8″ and 1/4″. They operate from 0 to 505 psig and are used for a variety of different applications, such as heating and automation. Most solenoid valves are normally-closed. The valve is closed in the solenoids rested or de-energized state and open when the solenoid is energized or current is applied to the coil. Fluid flow is blocked except when the solenoid valve is energized and opens. We have normally closed solenoid valves available with 24 volt and 120 volt coils. The high quality of construction materials used in these solenoid valves combined with extensive performance testing ensure maximum reliability and life. The valve bodies are made from brass, and come with Buna and Viton seals. It normally closed _ inched valve body.
