nylon butterfly valve without pin Product Features 1. Using non-pin nylon disc which is with good lubricity and effectively reduce operating torque 40% than ordinary pin butterfly valve 2.Good resistance of sealing(It’s 7 times more wearable than copper) It could abvirously prolong the service life of valve (It’s 3 times longer than ordinary centerline butterfly valve) 3.Nontoxic and antibacterial nylon materials is strictly according with green environmental protection requirement, It’s widely used for its resistance of alkali, salt, erosion and for organic compounds are inert 4.The advanced technology of Non-pin connection, which ensure the metal completely separated with the media, and improves the reliability of products 5.The price is far below than the stainless steel valves, significantly reduce project cost 6.Flange size of valves are available for different National Standards Name Of Vave PartsMaterialsBodyCI.
