High quality pn16 butterfly valve DN250

Product Details

Pneumatic butterfly valve is composed of double (single) acting piston type actuator and butterfly valve. Connecting methods are double-clip type and flange type and is valve seat applies rubber, fluoroplastics and stainless steel bead welding so as to significantly increase its range of application. Double-clip pneumatic butterfly valve has the advantage of simple structure ,small size and light weight .Pneumatic piston type actuator adopts low friction material ;with inside and outside surfaces of cylinder body conducted with hard anodizing anticorrosion treatment, service life of cylinder is significantly increased. Pneumatic butterfly valve has stable operating and is widely used in industrial departments like petrochemical, metallurgy, electric power, light industry and medicine.


For installation of butterfly valve, close the valve first and then install it to avoid any damage on sealing face of butterfly plate. Two pipe flanges should be in parallel so that the contact pressure between the valve and pipe flange is even .Inner bore of pipe flange should not be too big and make sure it’s not bigger than 5mm in case the pressed position on pressing plate is not right and the plate deforms and loses effect.
