Butt Welding Metal Seated Butterfly Valve
Firstly: The eccentric shaft deflected from the center line of sealing surface. Secondly: The eccentric shaft deflected from pipe and center line of valve. Thirdly: The unique design of eccentric seat oblique cone and the angle of centerline, makes the seat and sealing ring completely out from the door during the open and close.This structure adopted the cam effect, completely eliminating the friction, avoiding the possibility of wear and leakage.
Butt Welding Metal Seated Butterfly Valve
Uses and Charac Teristics
The butterfly valve is uesd as opening and closing, or adjusting medium on the pipe of high temperature, high pressure and fireproof. Its main charateristics as below: 1.Tight structure, small volume, light weight, smart operation and convenient using 2.The valve adopts triple eccentric resilence or multilayer metal seated structure to achieve zero leakage of sealing 3.This valve doesn't have flange, so it is convenient for thermalinsulation of the pipeline 4.The valve is characterised by hightemperature resistance, high pressure resistance, corrosion resistance and wear resistance,etc.
