Description
**Product Description:**
1. Pilot Operation: Internal or external pilot-operated options available;
2. Spool-type structure ensures excellent sealing performance and high responsiveness;
3. 3-position solenoid valves offer three center position configurations (exhaust center, pressure center, closed center);
4. Double-coil 2-position solenoid valves feature a memory function (maintains last position during power loss);
5. Precision-honed inner bore minimizes friction, enabling low actuation pressure and extended service life;
6. Maintenance-free operation without lubrication required;
7. Compatible with base-mounted manifold systems for space-saving installations;
8. Integrated manual override for simplified commissioning and diagnostics;
9. Multiple standard voltage options (AC/DC) to suit diverse applications.
**Category:** Solenoid Valves | **Brand:** AirTAC | **Series:** 4V200
**Model Example:** AirTAC 4V210-08 Pneumatic Solenoid Valve (220V AC/24V DC) – Directional Control Valve with Coil.
*(Note: Terminology optimized for clarity and industrial standards while retaining technical accuracy.)*
Installation Guidelines:
Mount with 15° maximum deviation from vertical axis. Use ISO 8573-1:2010 Class 3
compressed air (max 40μm particles, pressure dew point 3℃ below ambient).
Install downstream silencer (optional 4V-M5) for noise-sensitive environments.
