◆ Product Overview Flexible butterfly valve is a kind of a valve dual-use products,integrating the expansion pipe and flange butterfly valve.It can within a certain range can be axial expansion,and eliminate the pipe vibration and the heat-expansion and cold-contraction within a certain Angle to overcome the pipe misalignment caused by migration,to great convenience valve pipe installation and removal,thereby improving the economic benefit.
◆Use Telescopic butterfly valves are widely used in the temperature of 80℃ or less and nominal pressure of 1.6 MPa or less food,medicine,chemical,petroleum electric power,textile,paper and other water supply and drainage,gas pipeline to adjust flow and the role of intercepting medium.
◆Characteristics 1.Novel design,reasonable,unique structure,light weight,convenient operation,opening and closing quickly; 2.Telescopic butterfly valve for adjusting and intercepting effect,in addition to compensating pipe temperature difference of heat bilges cold shrink function can provide convenient for replacement and maintenance of valve installation; 3.Sealing parts,adjustable replacement,reliable sealing performance,etc.
