Rotary Valve vs. Butterfly Valve: 5 Critical Differences

H1: ROTARY VALVE vs Butterfly Valve: Choose the Right Flow Control
Featured Snippet:
"ROTARY VALVE excels in pressure maintenance (5:1 differentials) while butterfly valves suit low-pressure throttling. Consider material abrasiveness and required leakage rates when selecting."

ParameterROTARY VALVEButterfly Valve
Leakage Rate0.2-0.5%2-5%
Pressure HandlingUp to 10 barMax 3 bar
Maintenance Cycle6-12 months3-6 months
Ideal ApplicationPneumatic conveyingLiquid flow control

ROTARY VALVE systems feature tungsten carbide coatings for abrasive materials, while butterfly valves use rubber-lined discs for slurry applications
