Description
1/2 Inch 12V AC/DC Solenoid Valve Normally Closed
The 1/2 Inch 12V AC/DC Solenoid Valve is a durable and practical 2/2-way normally closed (NC) solenoid valve designed for controlling air, water, light oil, and gases. Its direct-diaphragm design allows it to operate directly under low-pressure conditions, making it suitable for a range of fluid and pneumatic control applications.
The valve features a durable brass body with an NBR seal, providing reliable construction for regular industrial use. Its 1/2-inch port size makes it suitable for systems requiring a compact connection for low-viscosity fluids and gases.
As a normally closed valve, the flow remains closed when the solenoid is not energized and opens when power is applied. The valve operates at 12V AC/DC, making it suitable for electrically controlled flow systems.
