High-flow directional control valve with dual coil operation, featuring triple-position control (extend/retract/neutral). Enhanced thermal stability design allows brief operation in high-temperature environments. Gold-plated terminals prevent oxidation in humid conditions. Requires 5μm filtered air with max 3% oil content.
- Pneumatic cylinder sequencing in assembly lines
- Clamping mechanisms in injection molding machines
- Multi-position actuator control in material handling systems
- Process valve switching in chemical dosing equipment
- Emergency stop systems with mid-position exhaust
Installation protocol:
Mount with M4 screws (recommended torque 1.2N·m). Maintain ≥15mm clearance
from heat sources. Use locknuts with 8-10 thread engagement turns for port
connections. Perform monthly manual override tests for spring function.
Critical note:
Do NOT use silicone-based lubricants - compatible with ISO VG32 turbine oil
only. Minimum 80% duty cycle required for continuous operation.
