What is the role of an isolation valve in a steam trap installation?

To regulate the temperature of the steam

To allow for maintenance of the trap

An isolation valve is essential in a steam trap installation as it allows for the maintenance of the trap without the need to shut down the entire system. This valve provides the ability to isolate the steam trap from the rest of the system, ensuring that technicians can safely inspect, repair, or replace the trap while minimizing disruption to the overall steam system. This capability is particularly important in industrial settings where continuous operation is often required, thereby ensuring maintenance work can be conducted efficiently and safely.

The role of the isolation valve directly supports the reliability and longevity of the steam system by facilitating regular maintenance and preventing potential issues from being overlooked due to accessibility challenges.
