Product Overview
The high-quality pneumatic dust-proof butterfly valve is designed for reliable performance in environments with high dust concentrations, powders, or granular media. Engineered with a robust sealing system and pneumatic actuation, it ensures tight shut-off, smooth operation, and extended service life in industries such as cement, food processing, pharmaceuticals, and material handling.
Key Features
1. Advanced Dust-Proof Design
Sealed bearing housing & stem protection prevents dust ingress, ensuring smooth operation even in abrasive conditions.
PTFE or EPDM seat with a dust-resistant lip seal minimizes particle buildup and maintains sealing integrity.
2. Pneumatic Actuation for Automation
Double-acting or spring-return pneumatic actuator (ISO 5211 mounting standard) for quick response (≤2 sec).
Optional solenoid valves, limit switches, and positioners for integration into control systems.
3. Durable Construction
Body materials: Carbon steel (WCB), stainless steel (CF8/CF8M), or coated options for corrosion resistance.
Disc options: Stainless steel, aluminum bronze, or epoxy-coated for wear resistance.
4. Bubble-Tight Sealing (Zero Leakage)
Soft-seat (ANSI Class VI) or metal-seat (Class IV) options for varying pressure/temperature needs (up to 200°C for EPDM).
5. Low Maintenance & Easy Installation
Lug or wafer-style flanges (ANSI, DIN, JIS standards) for flexible piping integration.
Self-cleaning disc design reduces clogging in powder applications.
Typical Applications
• Pneumatic conveying systems (cement, flour, fly ash).
• Dust collection & filtration units.
• Food-grade powder handling (FDA-compliant materials available).
Optional Enhancements
• Explosion-proof actuators (ATEX/Ex d certification) for hazardous areas.
• High-cycle versions for frequent operation.
• Sanitary finishes for pharmaceutical/food industries.
