Description
Technical Specifications
SPECS Concentric Butterfly Valves are widely apply to all kinds of industrial on-off control system. Compared to normal Globe Valve and Ball Valve, it has many advantages, like lightweight, low cost. With rapidly development of rubber material industry, soft seat butterfly not only is used to all kinds of water draining system, but also replaced to some flow control system by steps.
Concentric Butterfly Valve series are safety and low cost, it can apply to most of corrosive medium.So no medium contact with body and the material of it is steel or cast iron.lt is one of most economic valve under low and medium pressure.
