Ball & Cone Valve
Although the product line has changed ownership several times over its 90-year history, the GA Industries Rotovalve® Cone Valves have direct lineage to the original S.Morgan Smith cone valves of York, Pennsylvania.They are quarter-turn, full ported, metal-to-metal seated valves that can be used for isolation or pump control service on water, wastewater or sewage. __The Rotovalve® Cone Valve has a one-piece, top-entry body design with Monel to Monel metal to metal seating that shuts off tight in both directions.It incorporates a unique 'lift and turn' operating mechanism that ensures the plug rotates without seat contact for long term reliable operation. __When used for isolating or throttling service the valve can be actuated by a manual worm gear or an electric motor operator. __For pump control service, the Rotovalve® Cone Valve is typically actuated by a cylinder operator to control surges during pump start up and shutdown plus its full circular port and unobstructed waterway provides virtually zero headloss while pumping.The cylinder can be operated by water, oil or air and controls include normal and emergency solenoids, speed controls and limit switch.
