The 2W-160-15 N/O Solenoid Valve is a 2/2-way (two-way, two-position) normally open solenoid valve designed for the automatic control of air, water, gas, and light oil. When the solenoid coil is de-energized, the valve remains open to allow flow; when energized, the valve closes to stop the flow. Constructed with a durable brass body and a high-quality diaphragm, this valve provides reliable sealing, corrosion resistance, and long service life. It is widely used in water treatment systems, pneumatic automation, and fluid control applications.
