Stainless steel Butterfly valve

What is a stainless steel butterfly valve?

The butterfly valve is a type of valve that is used in the pipeline to shut off the connection. The stainless steel butterfly valve belongs to the family of quarter-turn rotational motion valves, and it is made from the stainless steel material. In other words, the ss butterfly valve is mostly used for regulating the water flow.

The 6-inch stainless steel butterfly valve comes with a disk that rotates to open or close the valve. The 2 inch stainless steel butterfly valve is mostly used in applications with a limited space. Here, the loss of pressure is lesser compared to the gate valve.

What does 150 psi wsp mean in cf8m butterfly valve?

150 psi wsp means that the working steam pressure in a cf8m butterfly valve is 150 psi. It is the maximum steam pressure which the stainless steel flanged butterfly valve can handle at the highest temperature rating.

Advantages of ss butterfly valve

There are several advantages of the stainless steel sanitary butterfly valve, like:

  • It is very lightweight and compact.
  • The stainless steel pneumatic butterfly valve has a very simple design and it is very cost-effective.
  • It is quick and very efficient too.
  • The pneumatic stainless steel butterfly valve helps with pressure control and it works for corrosive and viscous fluids. There is no cavitation or choked flow.
  • These valves do not have high-pressure throttling.

Stainless steel wafer type butterfly valve vs lug butterfly valve

The stainless steel wafer butterfly valve comes with four holes which aligns with the connected pipeline. The design of the stainless steel wafer type butterfly valve is such that they get clamped between the two flanges in the piping system. They mostly fit with all types of flanges.

The stainless steel lug butterfly valve has threaded tapered lug which is positioned on the flanges of the valve for making bolt connections. They are mostly used where the piping system ends.

SS 304 vs ss 316 butterfly valves

The primary difference between ss 304 and stainless steel 316 butterfly valve lies in their chemical composition. Due to the addition of molybdenum in the ss 316 grade, they resist corrosion better than the ss 304 butterfly valve in salt and other corrosive services.
The ss 316 butterfly valves are found in various corrosive and marine environments. However, the butterfly valve ss304 offers moderate corrosion resistance at an affordable price.

SS Butterfly Valves Advantages and Disadvantages

Advantages SS Butterfly Valves

Advantages SS Butterfly Valves

  • Compared to other valves, the compact design consumes a great deal less room.
  • small in size
  • It takes less time to open or close a quick operation.
  • sizes that are quite huge
  • High-pressure recovery after a low-pressure dip

 

SS 304 Flanged Butterfly Disadvantages

  • Throttling service is limited to low differential pressure
  • Cavitation and choked flow are two potential concerns
  • Disc movement is unguided and affected by flow turbulence

SS 304 Flanged Butterfly Disadvantages
