What is a Double Flanged Butterfly Valve?
A double flanged butterfly valve is a butterfly valve that has integral flanges built into the body of the valve. It is designed to mate up to two flange faces in pipework. In this case we are talking about ductile iron body (similar to cast iron but better advantages in terms of strength, elongation & life) center line butterfly valves. The center line refers to the location of the disc and shaft in relation to the body (there are other kinds of butterfly valves such as double & triple offset) where it is precisely in the middle. These valves can have different seat materials but the most common would be EPDM but others such as FKM, NBR or PTFE are also used. This type of body has the added advantage that the disc of the valve will do most of its turn within its own body width whereas wafer or lugged the disc will turn mostly in the pipe.
-
How does a Double Flanged Butterfly Valve work?
A double flanged butterfly valve works by the shaft rotating 90 degrees which will take the position of the disc in the flow from open to close (or vice versa). When it is closed a seal will be formed between the disc and the seat effectively stopping the flow of the media. When it is opened again the disc comes away from the seat and when it is fully open sits side (smallest surface area facing) on to the direction of the upstream flow. This 90 degree turn will take place from either a lockable handle (has a notch plate to stop at different positions within the 90 degree turn) or a gear box. Both have stops to prevent turning the valve past 90 degrees.
-
How long will my Double Flanged Butterfly Valve last?
Like any valve this depends upon the usage case of your butterfly valve, its environment, media and how many times it is cycled. For instance if it is on a clean wet media, in a clean environment and not cycled regularly the life will be decades. If it is on a corrosive media and in a dry application with a high cycle rate the life will be much shorter. We conduct regular lab testing and 6,000 cycles is a reasonable life cycle depending upon the application.
-
How do I install a Double Flanged Butterfly Valve?
These double flanged butterfly valves are designed to mate between two flanges. These will then be bolted together with the appropriate sized bolt and nut (varies depending upon size and flange standard). The seat of the valve also forms the gasket on the flanges so there is no need for a secondary gasket. The bolts should be tightened in a diagonal shape to avoid over tightening in one area. For a full list of instructions please visit our butterfly valve installation & maintenance guide.
-
What are typical uses of a Double Flanged Butterfly Valve?
These double flanged valves are very common in the civil water industry especially because most of our models hold a Watermark and Standards mark approval. They are also used for general purpose applications as long as the media, temperature and pressure are compatible.
-
How long will my product take to get to me?
This depends upon where you are based and the freight method chosen. If the express freight option is selected it is usually next day delivery to metropolitan areas in Australia for under 5kg. If free freight has been selected it will go by road freight which can be anywhere from 1 to 10 days depending upon your location. It usually averages 3 days.
-
What warranty do I get?
All of our products come standard with a 12 month warranty. The good news is we have very strict quality controls and all valves leave our warehouse tested (full material and testing certificates to API 598 are available) and inspected so there are rarely any issues. Also once your valve is in and operating it will most likely continue to do so for a very long time.
