Description
Product Description of AirTAC 4V300 Solenoid Valve:
1. Pilot type: Selectable internal pilot or external pilot configurations;
2. Spool-type structure ensures excellent sealing performance and responsive actuation;
3. Three-position valves offer three center position configurations (exhaust-closed/exhaust-open/pressure-center);
4. Dual-solenoid two-position valves feature memory function for sustained state retention;
5. Specially honed inner bore minimizes friction resistance, enables low operating pressure, and extends service life;
6. Maintenance-free lubrication system eliminates external lubrication requirements;
7. Manifold-compatible design allows modular assembly, optimizing space utilization;
8. Integrated manual override facilitates installation and commissioning adjustments;
9. Multiple standard voltage options available for flexible integration.
Category: Solenoid Valves | Brand: AirTAC | Series: 4V300
Maintenance protocol:
Lubricate pivot points every 2,000 operating hours using ISO VG32 turbine oil.
Ensure exhaust ports face downward when vertical mounting is unavoidable.
Critical note:
Do not apply silicone-based lubricants - incompatible with NBR seals.
Maintain minimum 85% duty cycle to prevent coil overheating.

- Clamping/unclamping mechanisms in CNC machining centers
- Double-acting cylinder control in automated assembly lines
- Pneumatic brake systems for material handling equipment
- Position holding in semiconductor wafer handling robots
- Air logic circuits requiring intermediate positions
Maintenance protocol:
Lubricate pivot points every 2,000 operating hours using ISO VG32 turbine oil.
Ensure exhaust ports face downward when vertical mounting is unavoidable.
Critical note:
Do not apply silicone-based lubricants - incompatible with NBR seals.
Maintain minimum 85% duty cycle to prevent coil overheating.
