Central Lug Style Butterfly Valve
The central lug style butterfly valve's function is to retain a seal to protect against dual-directional pressure differential in the flow of fluid. In other words, the lug version of butterfly valves was designed to hold a tight seal, safeguarding against bi-directional pressure differential in order to avoid any backflow in systems that have been manufactured for uni-directional flow. Lug butterfly valve is accomplished by using a tightly fitted seal, such as an O-ring, gasket, precision machined, along with a flat valve face on the downstream and upstream sections of the valve.
The lug type butterfly valve in ductile iron, carbon steel or stainless steel is available with various seal options from Buna, EPDM, Teflon or Metal Faced. Handle or wheel options are available. Additional mounting of actuator limit switches And gear boxes are optional. A lug butterfly valve's function is to retain a seal to protect against dual-directional pressure differential in the flow of fluid.
