DN80(3 Inch) Ductile Iron Butterfly Valve with Teflon Seat Manufacturers and Suppliers

Ductile Iron Butterfly Valve with Teflon Seat Overview

Butterfly valve is a quarter-turn rotational motion device that utilizes a rotary disc to allow, obstruct, or control the flow of fluids in a piping system.

Ductile iron is a more modern iron alloy that is made with nodule-shaped graphite. This gives the material excellent ductility, so it will not necessarily break when bent. When it comes to pressure, ductile iron butterfly valves also use pressure classes: 150 and 300. At standard outdoor temperatures, class 150 ductile iron keeps a seal up to 250 psi. Class 300 can stand up to pressures as high as 640 psi.
Ductile iron has excellent corrosion resistance, tensile strength, and yield strength. Ductile iron is a strong and reliable material for pipes, fittings, and valves.

Valve seat adopts Teflon (PTFE), the advantage of Teflon seat butterfly vave is that it is extremely resistant to a wide range of chemicals. Because of this compatibility, Teflon seals are often preferable over ones made completely of carbon–they provide better lubrication with a higher corrosion resistance.
