What is an Isolation Valve?

An Isolation Valve is a type of valve that will completely obstruct the path of gas or water to certain sections or the complete boiler system. An isolation valve will usually be found on the connecting pipes across the bottom of the boiler.

There are different types of an Isolation Valve used on a boiler by the way they are opened and closed, generally they are Tap Isolation Valve, Wheel head Isolation Valve or Lever Isolation Valve.
