High-sensitivity pressure regulator featuring dual-chamber design for stable output under fluctuating input pressures. The LN variant includes a locking collar to prevent accidental adjustment, with anti-vibration gauge mounting. Includes built-in silencer for reduced exhaust noise (68 dB(A) max). Requires 5μm filtered air.
- Semiconductor manufacturing equipment
- Precision pneumatic measurement instruments
- Automated packaging line pressure control
- Medical gas pressure regulation systems
- Laboratory pneumatic tool stations
Installation guidelines:
Mount vertically with arrow direction matching airflow. For optimal performance,
install downstream filter (5μm) and maintain 15mm clearance for gauge visibility.
Lubricate adjustment thread annually with silicone grease.
- Pull up locking ring to unlock adjustment knob
- Rotate clockwise to increase pressure (max 2 full turns from zero)
- Allow 3-second stabilization after adjustment
- Push down locking ring to secure setting
