- Plastic injection molding machine air circuits
- CNC machine tool pneumatic tool changers
- Food processing equipment (compatible with food-grade lubricants)
- Textile machinery air jet control systems
Installation guidelines:
Mount in vibration-controlled environments (≤1.5G). Maintain minimum
30mm clearance above valve for heat dissipation. Use copper-free
sealing tape for pipe connections. Perform monthly manual cycling
during standby periods.
