2W Normally Closed Solenoid Valve with Power-Off Closure and Power-On Opening

The 2W normally closed solenoid valve is a two-position two-way normally closed valve, meaning it has two ports: an inlet called the valve cavity and an outlet called the valve body orifice. It is a simple solenoid valve design that can be used in applications where it is necessary to remain closed when the power supply is disconnected, such as in liquid or gas control systems.

Simple and reliable: The structure is uncomplicated. It offers a long service life and high reliability.
Easy to control: It can be remotely controlled or automated through a simple electrical control system.
Energy-saving: It does not consume electrical energy while maintaining a closed state, only consuming power when it is necessary to open the valve.
