Ductile Iron Butterfly Valve

Whether you are replacing or purchasing a new ductile iron butterfly valve, you should always look for one that has been ANSI/NSF 61 & 372 certified. These valves are extremely durable, making them an excellent choice for industrial applications.

Cost of a ductile iron gate valve

Purchasing a new valve can be costly. A ductile iron butterfly valve can be more expensive than a cast iron valve. However, there are some advantages to using ductile iron.

Cast iron is an older alloy than ductile iron. Unlike cast iron, ductile iron corrodes less easily. It has a high tensile and yield strength. It is ideal for high-pressure applications.

Ductile iron valves come in a variety of sizes. They are available in two pressure classes. The Class 150 ductile iron seals up to 250 psi while the Class 300 ductile iron seals up to 640 psi.

The resilient wedge gate valves made of ductile iron are intended for use in sewage, fire protection, and potable water applications. The resilient wedge design ensures that there is no leakage. It comes in a variety of sizes and includes integrated lifting devices.

General service butterfly valve 313207

The Cameron DEMCO manual butterfly valve 313207 is an excellent choice for dealing with water or chemically inactive liquids. This valve has a one-piece body, a dry stem journal, and self-centering in an ASME Class 150 flange pattern. It comes in a variety of sizes and is perfect for oil and gas applications.

The butterfly valve is made of ductile iron, which means it will not lose shape under extreme pressure. In certain environments, it also provides superior corrosion resistance.

The wetted surface of the valve must be weight-protected from lead. It must also be chemically treated for disinfecting purposes and be able to withstand a chlorine residual concentration for 24 hours.

The DEMCO butterfly valve has a bi-directional flow way, meaning that the valve is designed to seal against both the flange faces and the full disc opening. It also has a 0 degree disc angle, so it opens and closes in the same direction. It is detachable for inspection and replacement. It can also be cleaned with a lubricant that does not contain hydrocarbons.
