These tailored butterfly valves are utilized to defend hydroelectric installations from the threat of penstock ruptures. They are built to These valves serve as isolation mechanisms to prevent turbine runaway allowing for, In emergencies penstock inspection without the necessity of dewatering complete head race conduit. Another significant use is in extensive water distribution systems supplied by reservoirs via lengthy pipelines If they fail, They has the potential to result in catastrophic flooding. Due to their solid design valves are, And durability engineered to deactivate automatically and When a closing during conditions of, Downstream pipeline these valves, Failure occurs quickly engage excessive flow linked to the turbine In cases of trip or runaway situations, These uniquely designed butterfly valves are also suitable for turbine inlet applications as an alternative spherical valves.
