wafer butterfly valves SS gearbox operated can both isolate and regulate flow in a system. These valves work in similar fashion to a ball valve, allowing for a fast shutoff when necessary. They are a bit more affordable than ball valves of similar sizes, and also weigh less, so they do not require as much support as ball valves. waferbutterfly valves SS gearbox operated can be used in a variety of applications where precise flow pressure is not required, such as irrigation, food processing, chemical processing, manufacturing and home plumbing systems.
NOTE: Most butterfly valve installs require flanges and a stud kit for installation.
