Concentric Flanged Butterfly Valve

Detail

Flanged type concentric Rubber Lined Butterfly Valve


SENSI Concentric butterfly valves with concentric design are widespread used due to their relatively low cost and simplicity of design and maintain.


Function:

Low cost, reliability, small dimensions and low weight of valve.The corrosion resistant material can prolong the lifespan of valve, the sealing parts are replaceable, and the sealing performance can reach to zero leakage, which make it applicable for special working condition.
