When it comes to configuring steam systems there are a number of factors to consider to determine what parts are needed and where they should be placed.

In the sketch above, can you spot:

• Which piece of equipment shown is not recommended?
• Which two major pieces of equipment are missing?

Know the answers? If not, here they are:

 

Answer #1 – Quick opening solenoid valves are not recommended for steam service due to the potential for water hammer and thermal shock, both of which decrease the longevity of equipment and can lead to safety issues.

Answer #2 – The two major pieces are a safety value and a vacuum breaker. A safety valve is required downstream of the pressure reducing valve by section VIII of ASME code. As we describe in our previously posted article on vacuum breakers, a vacuum breaker is recommended downstream of the coil and above the steam trap for complete condensate drainage under all operating conditions.
