Classification of Valves Used in Piping Systems 1 Comment

Valves exceed any other piping component. Estimates reveal that a substantial portion,

approximately 8-10%, of the total capital expenditure of the chemical process industry is

used for the procurement of valves. In terms of the number of units also. Hence,

proper thought should be given f or the selection of valves. The first step in the selection is

to determine exactly what function the valve is expected to perform after it has been

installed.

Valves are installed on equipment/ piping to perform any one of the below mentioned

functions.

Classification of Valves:

1. Based on functions:

Functions of Valves

The design of the valves is done in such way as to perform any of the above functions.

The type of valves used can be classified in the following categories.

Isolation valve

Non return valve

Check Valve

Special Purpose Valve

Multi-port Valve

Flush Bottom Valve

Float Valve

Foot Valve

Line Blind Valve

Pressure / Vacuum Relief Valve

2. Based on the end connections:

The valves can further be classified based on the end connections. End connection means

the arrangement or attachment of the valves to the equipment or to the piping. The types

of

end connections are:

Screwed ends.

Socket weld ends

Flanged ends

Butt weld ends

Socketted ends

Wafer type ends

3. Based on the materials of construction:

The valves could also be classified based on the materials of construction. There can be

any number of combinations possible with the materials of construction. It is for the

piping engineer to select the same in consultation with the process engineer to suit theprocess fluid.

The environment in which the valves are installed is also to be considered for selection

of materials of construction. However, the most commonly available materials are:

Cast Iron

Bronze

Gun metal

Carbon Steel

Stainless Steel

Alloy Carbon Steel

Poly Propylene UHMW-PE,UHMW-HDPE etcSpecial Alloys

Body could also be lined with elastomer so that process fluid will not be in contact with

the metal.

The valve could also be classified based on the type of construction. Valve manufacturers

offer endless varieties of construction. Based on the operation, valves can be broadly

classified as operated valves and self-operated valves. Mainly the check valves are self-

operated and all other types come under operated valves.
