Butterfly
Overspeed butterfly valve
IG-100SV series valves are bi-eccentric and of machine-welded construction custom made and adjust themselves perfectly to the hydraulic conditions of the facility, producing the least possible loss of charge. The opening is made by means of an oleo-hydraulic cylinder and the closing by the action of a counterweight. The control system is a fully mechanic overspeed blade detection system which can be combined with electrical or oleo-hydraulic systems. They are specially designed to act as emergency closing devices.
