High-flow compact solenoid valve featuring manual override capability and zero pressure differential operation. The brass core tube design ensures stable magnetic force distribution, while the optimized spool structure minimizes pressure loss (ΔP≤0.02 MPa). Requires 5μm filtration with oil mist lubrication (ISO 8573-1:2010 Class 4.4.3).
- Pneumatic cylinder sequencing in assembly lines
- Vacuum generator control in material handling systems
- Coolant flow regulation for CNC machining centers
- Compressed air management in semiconductor fab tools
- Automated bakery oven door actuators
Installation protocol:
Mount with torque ≤1.5N·m using backup wrench. For horizontal mounting,
orient coil upward. Install downstream of 40μm filter regulator lubricator (FRL) unit.
Perform 5-minute dry cycling before initial operation.
