Getting Assistance From Butterfly Valve Suppliers

Perhaps the most undervalued aspect of working directly with experienced butterfly valve suppliers is the problem solving and real-world experience and expertise these professionals can provide.

This is very different than buying through a website or using a general contractor type of supply center. Without the expertise of butterfly valve suppliers, you may find that you are missing out on the option to find the most effective design and sizing of the valve to suit your specific application requirements.

Not all butterfly valves are the same in their design and their application. In general, all of these valves allow the obturator (usually a circular plate or disc) to turn on an axis in the valve at right angles to the direction of the flow. When fully open the disc is parallel to the flow, allowing full flow through the system. When turned to the off position, the disc moves 90 degrees perpendicular to the flow, shutting off immediately.

Differences to Consider

By using butterfly valve suppliers to help to determine the best design to consider for your application, it is possible to avoid common mistakes. For example, there are some valves that are designed with a rubber seat. This is instrumental in sealing the valve. This type of valve is most often referred to as a resilient-seated butterfly valves.

A double-offset butterfly valve is an ideal option for high-pressure applications. The disc is positioned in front of the stem, with a second stem off to the center of the disc. This design limits the rubbing of the disc on the seat during movement, extending the life of the valve.

Other essential differences to consider in the butterfly valves will be the material used in the manufacturing of the valve. For high corrosion resistance, coating the wetted surface of the valve can eliminate the risk of corrosion, further extending the life cycle of the valve as well as reducing any maintenance requirements.
