Isolation Valves : Piping Engineering

Isolation valves are integral part of Piping systems. in this section we are going to discuss the various types of valves, it's body of construction, functions, applications along with advantages & disadvantages.

• Gate valves

• Ball valves

• plug valves

• Butterfly valves

• DBB valves

Pictorial views of valves based on isolation have been captured and explained. Session on regulation valves have also been prepared on similar manner.

Frequently Asked Questions:

What is Isolation Valve?

An isolation valve is a valve in a fluid handling system that stops the flow of process media to a given location, usually for maintenance or safety purposes.

What is an isolation valve used for?

Isolation valves are a key component in any fluid system as they are used to stop the flow of fluid into a particular area of the system. They are also sometimes used to manually control the flow of the fluid.

Which valve is an isolation valve?

The two most common isolation valves on the market today are ball valves and gate valves.

Can isolation valves leak?

The most common reason for an isolation valve to leak would be age-related wear and tear

What is isolation in piping?

Positive Isolation: Isolation of process piping, equipment or vessels from hazardous materials (vapors, liquids, or solids) such that it is impossible for hazardous materials to enter the work area.

What type of valve is used to isolate pressure gauges?

Ball valves (90° angle) protect the pressure gauge by dampening pressure surge during opening and isolating the pressure gauge entirely.

Which valve is best for isolation?

The two most common isolation valves on the market today are ball valves and gate valves.

Where are isolation valves required?

An isolating valve is required to be located at: each water main. or near the property boundary.

Is stop valve same as isolation valve?

Shut-off valves, also known as isolation valves, are able to close flow to – or isolate – loops of heads.

Is a check valve An isolation valve?

Although check valves can effectively shut off reverse flow, they should never be used in place of an isolation valve to contain live steam
