Industrial-grade pressure regulator featuring dual-chamber design for stable output under fluctuating supply pressures. The hexagonal knob with torque limiter prevents accidental adjustments, while the integrated relief valve enables quick pressure release. Chrome-plated spring chamber resists corrosion in humid environments.
- CNC machine tool pneumatic systems
- Semiconductor manufacturing equipment
- Automated assembly line pressure control
- Food processing pneumatic circuits (FDA-compliant variants available)
- Medical gas pressure regulation (requires special certification)
Installation protocol:
Mount upstream of lubricators using two wrenches on flat wrench surfaces.
Always install downstream filter (40L/min capacity minimum). For vertical
mounting, orient relief valve downward. Allow 15mm clearance for gauge
installation and knob rotation.
