Industrial-grade directional control valve featuring bi-stable latching mechanism for energy-efficient operation. The dual-coil design maintains position without continuous power, with hardened brass body for chemical resistance. Includes manual override and LED status indicator. Requires ISO 8573-1:2010 Class 3 compressed air (max 50mg/m³ oil content).
- Automated assembly line clamping systems
- Plastic injection molding machine actuators
- CNC tool changers with position memory
- Battery production vacuum handling
- Textile machinery tension control
Installation protocol:
Mount on vibration-dampening brackets with M5 fasteners (3.5Nm torque).
Maintain 15cm clearance above valve for heat dissipation.
Use AirTAC XF2500 series lubricator for optimal seal performance.
