Vacuum System Control
Precision pressure regulation in semiconductor manufacturing, vacuum coating, and medical equipment
Maintains stable vacuum levels (±1% accuracy) for pick-and-place systems
Localized Pressurization
Creates isolated high-pressure zones in low-pressure networks
Enables compact pneumatic tools (e.g., precision pressing in automotive assembly)
Energy-Efficient Circuits
Reduces compressed air consumption by 15-30% in single-acting cylinders
Stabilizes pressure fluctuations in large-scale air supply systems
Special Environments
High-temperature (<80°C) and cryogenic (>-30°C) operations with FKM/NBR seals
Chemical-resistant metal housing versions for corrosive atmospheres
Pressure Limits:
Maintain outlet pressure ≤ 90% of inlet pressure
Install safety relief valves downstream
Flow Direction:
Strictly follow arrow markings on valve body
Avoid reverse installation
Filtration:
Mandatory upstream filter (5μm or finer)
Prohibited: Upstream lubricators (use downstream if required)
Environment:
Shield plastic models from UV exposure
Reserve 60mm clearance under maintenance plug
Startup Sequence:
Fully counterclockwise rotation before system pressurization
Slowly open supply valve while monitoring pressure gauge
Pressure Setting:
Turn clockwise gradually to desired pressure
Never exceed gauge's max pressure (typically 60% of full scale)
Safety Protocol:
Always stand sideways during adjustment
Confirm leak-tightness with soap solution
Task | Frequency | Action |
Filter check | 500 hrs/month | Replace clogged elements |
Seal inspection | 6 months | Verify integrity of diaphragms/O-rings |
Calibration | 12 months | Verify ±1.5% pressure accuracy |
Leak test | 12 months | Confirm <0.1% flow leakage (VI class) |
Failure Prevention:
Pressure spikes: Clean orifice holes quarterly
Output instability: Replace worn springs/check feedback ports
Persistent leaks: Inspect valve seat for damage/contamination
Key Advantages:
Lightweight modular design (20% lighter vs predecessors)
Rc1/4 to Rc3/8 ports with 60-150 L/min flow capacity
±0.5% outlet stability during ±10% inlet fluctuations
5+ year MTBF with proper maintenance
