Manual Butterfly Valves

Butterfly valve is a quarter-turn valve used to regulate flow. Butterfly valves are similar to ball valves but have several advantages. They are small and, when actuated pneumatically, open and close very quickly. The disc is lighter than a ball, and the valve requires less structural support than a ball valve of comparable diameter. Butterfly valves are very precise, which makes them advantageous in industrial applications. They are quite reliable and require very little maintenance.
