Description
1/4 Inch 220V AC Solenoid Valve Normally Closed
The 1/4 Inch 220V AC Solenoid Valve is a compact and durable 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 variety of fluid and pneumatic control applications.
The valve features a durable brass body and NBR seal material, providing reliable construction for regular industrial use. With a 1/4-inch port size and 2.5 mm flow pore diameter, it is suitable for systems requiring a compact connection for low-viscosity fluids and gases.
As a normally closed valve, it remains closed when the solenoid is not energized and opens when electrical power is applied. The valve operates at 220V AC, making it suitable for electrically controlled flow systems.
