What are Butterfly Valves?
A butterfly valve is a particular type of valve that uses either a circular vane or a disc as the shut-off mechanism. Butterfly valves have a quick opening/closing quarter-turn mechanism that is used to control the flow of liquid through a piping system. They typically pivot on axes perpendicular to the direction of flow inside the flow chamber. Compared with ball valves, butterfly valves do not have pockets to trap fluids when the valve is in the closed position. Butterfly valves are frequently used as throttling devices, controlling the levels of flow in various positions: entirely closed, entirely open or partially open. They can control various substances of air, liquid or solid currents and are situated on a spindle that allows for flow in a single direction. Butterfly valves are offered in many sized diameters, resulting in different flow rates. Smaller valve assemblies may be used where space is limited. Knowing the pipe dimensions, desired flow rate and material is important wh
