The BFS series of butterfly valve has a 316 Stainless Steel body, 316 S.S disc and a PTFE coated NBR seat making them suited to a wide range of high end applications. These wafer butterfly valves will fit all standard flanges and are operated by either a lever (304 Stainless Steel) or gear box (FBE coated Ductile Iron however full stainless steel gear box is available upon request). The unique bonded catridge design gives them a longer life span, allow vacuum to be run through them and makes them replaceable if ever the need should arise. Common applications include food industry, chemicals, pharmaceuticals and other industrial applications.

What is a Wafer Stainless Steel Butterfly Valve?
A stainless steel wafer butterfly valve is a butterfly valve that is designed to clamp between two flanges without the need for the bolts to go through threaded holes on the body of the butterfly valve. It sits like a 'wafer' between the flanges and therefore fit multiple flange standards unlike lugged which will be designed to fit only one standard. In this case we are talking about 316 stainless steel center line wafer 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 have a PTFE coated NBR seat.

How does a Wafer Stainless Steel Butterfly Valve work?
A 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 Wafer Stainless Steel 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 Stainless Steel Butterfly Valve?
These wafer butterfly valves are designed to clamp between two flanges. The bolts will pass through from one flange to the other to give the clamping force on the valve and keep it in position. 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 Stainless Steel Butterfly Valve?
These are mainly used in corrosive environments or areas where a stainless steel body is needed. They can really be used in any application where 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.
