Description

The General Purpose Solenoid Valve – Normally Closed (NC) is one of the most widely used valves in industrial control systems, providing automatic and precise control of liquid and gas flow. Operating on the Normally Closed (NC) principle, the valve remains closed when power is disconnected and opens automatically when the solenoid coil is energized, ensuring a high level of safety and operational reliability.

Its fast response, simple operation, and low maintenance requirements make it an ideal solution for a wide range of industrial automation and process control applications.

Performance Advantages

The General Purpose Solenoid Valve provides fast and accurate flow control, improving the efficiency of industrial systems while reducing energy consumption. Its Normally Closed (NC) design automatically stops the flow during power failure, enhancing system safety and protecting equipment from unintended operation.

⸻

Installation & Maintenance

The valve should be installed according to the flow direction indicated on the valve body. It is recommended to install a strainer upstream of the valve to protect it from contaminants and extend its service life. Regular inspection of the solenoid coil, internal components, and sealing elements is also recommended to ensure reliable long-term performance.
