Many engineers struggle to select valves for large pipelines. OUWEI sorts out 4 core strengths of butterfly valves compared with gate valves: 1. Ultra-compact face-to-face length saves installation space; 2. 60%-75% lighter weight cuts transportation and structural costs; 3. Quarter-turn quick open/close for emergency isolation; 4. Fewer moving parts reduce long-term maintenance expense.
