Airtac 2W250-25 220V Solenoid Valve – DN25 1-Inch 2/2 Normally Closed Valve
✅ Airtac 2W250-25 220V is a 2-way, 2-position solenoid valve from the Airtac 2W series, designed for automatic ON/OFF control of fluids in industrial and commercial piping systems. The model features a 1-inch DN25 connection and an AC220V coil, making it suitable for water, air, oil and other compatible media.
✅ The valve operates by an electromagnetic mechanism with a normally closed (NC) configuration. When the coil is de-energized, the valve remains closed and blocks the flow. When 220V AC power is supplied, electromagnetic force activates the internal mechanism and opens the flow passage.
✅ The 2W250-25 features an orifice of approximately 25mm, making it suitable for applications requiring a larger flow passage than smaller 2W models. The DN25 – 1-inch connection size is widely used in water, pneumatic, oil and industrial piping systems.
✅ The valve body is made of brass, providing suitable mechanical strength for many common fluid-control applications. Depending on the actual version and operating conditions, sealing and internal materials may vary according to the medium requirements.
✅ With its 2/2-way configuration, the Airtac 2W250-25 220V is designed for straightforward ON/OFF flow control. The valve can be controlled by an electrical signal from a controller, switch, relay or other automation equipment.
✅ Airtac 2W250-25 220V can be integrated with filters, regulators, controllers and other fluid-control components to create a complete automatic piping system. Correct flow direction, coil voltage and media compatibility should be considered during installation.
