- CNC tool changers and coolant control
- Food processing pneumatic actuators
- Battery manufacturing vacuum breakers
Installation guidelines:
Mount in vibration-free locations using M4 mounting screws (not included).
Maintain 15° maximum deviation from vertical orientation.
Install upstream 0.5-1m after lubricator for optimal performance.
Replace seals every 50,000 cycles in high-humidity environments.
