Description
The Belven BV12S Low Torque Lug Butterfly Valve is a specialized high-efficiency valve designed for automated control systems and high-cycle applications. Featuring a continuous single-shaft drive mechanism and optimized disc geometry, the BV12S delivers ultra-low breakaway operating torque and extended actuator life cycle performance under PN16 line pressure.
Key Features & Design Highlights
- Single Continuous Shaft: Through-shaft drive design provides superior rigidity, eliminates hysteresis, and ensures precise disc positioning.
- Ultra-Low Torque Profile: Specially engineered disc contour and seat contact zone reduce required seating/unseating torque by up to 30%.
- Threaded Lug Body: Threaded lug configuration supports full dead-end pipe termination and downstream equipment maintenance under pressure.
- Actuator Friendly ISO Pad: Standardized ISO 5211 mounting flange minimizes stress on electric/pneumatic actuator gear trains.
- Zero-Leakage Sealing: Resilient seat liner ensures EN 12266-1 Rate A zero-leakage shut-off.
Recommended Applications
Optimized for automated HVAC control valves, district cooling networks, automated process plants, and high-frequency cycling lines.
