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 protocol:
Mount in vibration-free locations using M5 mounting screws (max torque 2.5N·m).
Maintain ≥20mm clearance around coils for heat dissipation. Use AirTAC
EV-2/2.5 silencers for exhaust ports in food-grade environments.
Critical note:
Always install downstream of 40μm filter regulator. Avoid continuous
energizing >60 minutes in ambient temperatures above 60℃. Parallel diode
required for DC coil surge protection.

High-flow directional control valve featuring dual coil configuration for bistable operation. The anodized aluminum body with hardened brass ports ensures corrosion resistance in humid environments. Optimized spool design achieves 30% faster response than standard 4V200 models. Requires ISO 8573-1 class 3 compressed air (max 5mg/m³ oil content).
Industrial Applications:
- Pneumatic cylinder sequencing in automated assembly lines
- Clamping/unclamping mechanisms in CNC machining centers
- Material handling systems with dual-acting actuators
- Textile machinery requiring bi-stable position memory
- Plastic injection molding machine ejectors
