Valve End Connections

Just considering the size and design is not important, it is also important to consider the valve end connections. So, below is discussed a valve end connection about which one must know:

Common Valve End Types:

The implication of such valve end connection is due to the end connection compatible with the piping. At the same time there is also a functional characteristic to the common end type which might make one valve more suited to the requirement as compared to the others.

The common valve end connections includes some more varieties which needs to be understood:

Screwed or Threaded:- Mostly used in the connections of an instrument or sample points
Flanged:- One of the most common ends for piping use
Butt Welded:- Widely used in high-pressure or high-temperature operations
Socket Welded:- Highly used in small bore piping where threaded connections are not permitted
Wafer and Lug:- It is commonly used for compact valves installed in systems with limited space

Importance Of Selecting The Valve Material

Depending on the type of use the material with which the valves are build is a critical aspect which ensures the safe operation and reduces the maintenance and replacement cost during the entire life of your operation.

It is commonly known that the valves made of stainless steel are excellent options in a range of processing environment which also includes the corrosive media like the chemicals, saltwater, and acids with complete sanitation standards and processes by using a quite high pressure or high temperature.

Other than this selecting a correct body material should be evaluated for the chemical compatibility which is of utmost importance. In case there are elastomers present in your valve there should be a complete evaluation for its chemical compatibility as well as the limitations of pressure and temperature.

Valve Standards

Selecting a standard of the valve is also important but for that you might need to find that the valve must adhere to the particular standards in order to meet the regulatory requirements for safety, sanitation and other concerns. There are various standard organizations and potential regulations amongst which some common general standard organizations include:
