High-flow directional control valve with dual coil latching mechanism, engineered for heavy-duty pneumatic systems requiring position memory. Features brass alloy body with hard-anodized aluminum solenoid housing, optimized for rapid cycling (up to 5Hz). Requires 5μm filtered air with ISO VG32 turbine oil mist lubrication (optional).
- Automated production line clamping systems
- Plastic injection molding machine actuators
- CNC machine tool pneumatic tool changers
- Automotive brake testing equipment
- Foundry air cylinder sequencing
Installation guidelines:
Mount horizontally with coil axis vertical (±30° tolerance).
Use flexible tubing connections to prevent vibration transfer.
Minimum 100mm clearance above valve for heat dissipation.
Apply thread sealant on male ports (PTFE tape prohibited).
- Pre-charge system to 0.3MPa before initial activation
- Install moisture separator upstream (mandatory in humid environments)
- Verify voltage stability within ±10% during cycling
- Replace seals every 5 million cycles (NBR) or 8 million cycles (optional FKM)
