What is the maximum allowable operating pressure for the safety valves on a miniature hobby locomotive?

The maximum allowable operating pressure for the safety valves on a miniature hobby locomotive is typically regulated to ensure safe operation. Setting this limit to no more than 10% above the operating pressure ensures that the safety valves will open at a pressure that is still safe for the system while providing a margin for fluctuations in the operating conditions. This standard helps prevent accidents or equipment failure due to excessive pressure, which could pose significant risks.

Maintaining this 10% limit ensures that safety remains a priority, and the system is designed to operate effectively within a specific pressure range. Ensuring safety valves open before reaching dangerously high pressures promotes both the safety of the equipment and the individuals operating the locomotive.
