Airtac 4V210-08BT-W External Pilot Solenoid Valve (DC24V, NPT 1/4) | Vacuum Compatible

Product Description

The AirTAC 4V210-08BT-W is a 5-port, 2-position, single-solenoid directional control valve designed for pneumatic and vacuum-control applications. This configuration features a DC24V coil, NPT 1/4 working ports and an external pilot-air connection.

Unlike an internally piloted valve, the 4V210-08BT-W receives its pilot pressure from a separate compressed-air supply. This allows the valve to switch reliably when the main circuit operates under vacuum or does not provide sufficient pressure for internal piloting.

It is suitable for vacuum handling equipment, pick-and-place systems, suction-cup control, packaging machinery, automated assembly lines and other industrial applications requiring electrically controlled directional switching.

Product Configuration

• Brand: AirTAC

• Model: 4V210-08BT-W

• Valve Type: External-pilot solenoid valve

• Valve Function: 5-port, 2-position

• Operation: Single solenoid with spring return

• Coil Voltage: DC24V

• Main Port Size: NPT 1/4

• Pilot Type: External pilot

• Application: Pneumatic and vacuum systems

• Vacuum Compatible: Yes

• Working Medium: Clean, filtered air

Key Features

1. External pilot operation: Uses an independent pilot-air supply for reliable switching when the main line is under vacuum or low pressure.

2. Vacuum-compatible configuration: Suitable for controlling vacuum actuators, suction cups and vacuum-handling circuits.

3. Single-solenoid design: Electrically actuated in one direction and automatically returned by spring when power is removed.

4. DC24V coil: Compatible with commonly used industrial automation control systems.

5. NPT 1/4 ports: Designed for equipment and piping systems using NPT-threaded fittings.

6. Manual override: Allows commissioning and functional testing without energizing the coil.

7. Compact construction: Suitable for installation in control cabinets, pneumatic panels and automated machinery.

8. Fast directional switching: Supports responsive and repeatable pneumatic control.

Typical Applications

• Vacuum suction-cup control

• Pick-and-place equipment

• Vacuum lifting and handling systems

• Packaging and labeling machinery

• Automated assembly equipment

• Robotic end-of-arm tooling

• Material transfer systems

• General industrial pneumatic circuits

Important Installation Information

The external pilot port must be connected to a separate compressed-air supply that meets the valve’s pilot-pressure requirements. The main working ports may then be connected to the vacuum circuit as required.

Please confirm the port identification shown on the valve body before installation. Use compatible NPT fittings, ensure that the supplied voltage is DC24V, and prevent pipe sealant or debris from entering the valve.

Ordering Notice

Please verify the complete model 4V210-08BT-W, coil voltage, port thread, external pilot configuration and vacuum-system requirements before placing an order. This model should not be replaced with a standard internally piloted 4V210 valve when the application requires vacuum operation or an independent pilot-air supply.
