Structural Forms
1. Normally Closed (Air-to-Open): Automatically closes when air supply is cut off, opens when air supply is restored; commonly used for equipment safety.
2. Normally Open (Air-to-Close): Automatically opens when air supply is cut off, closes when air supply is restored; suitable for continuous operation.
3. Double-Acting: Bidirectional air supply control; faster start/stop response; suitable for high-frequency start/stop scenarios.
Core Advantages
• Straight-through angled flow channel; minimal flow resistance; smooth media flow; less prone to material accumulation and blockage.
• Pneumatic drive; rapid start/stop and sensitive response; suitable for frequent on/off operations.
• All-stainless steel valve body; resistant to moisture and mild corrosion; high hygiene standard.
• Self-cleaning seal design; high temperature resistance; anti-scaling; highly adaptable to steam and hot water conditions.
• Compact size; easy installation; can be installed vertically or horizontally; simple maintenance.
Applicable Operating Conditions
• Water treatment industry: Automatic control pipelines for pure water, wastewater, and circulating water.
• Steam and Thermal Power: High-temperature steam, hot water transfer, and boiler auxiliary pipeline switch control.
• Food and Pharmaceutical: Beverage, pharmaceutical, and daily chemical hygiene-grade fluid transport systems.
• Chemical and Light Industry: Automated shut-off and regulation of mildly corrosive liquids, gases, and oils.
• Industrial Equipment: Dryers, sterilization equipment, printing and dyeing machinery, and HVAC automation systems.
