To what pressure should the high pressure control be adjusted?

The high pressure control should be adjusted to match the setting of the pressure relief valve. This is crucial for maintaining safe operating conditions within a steam system. The pressure relief valve is designed to prevent over-pressure situations that can lead to equipment failure or even dangerous situations, so having the high pressure control set to the same level ensures that the system operates efficiently and safely.

When the high pressure control is set to the same pressure as the relief valve, it creates a coordinated safety mechanism that allows the system to function without exceeding safe pressure limits. Adjusting the high pressure control to any of the fixed lower pressure options could potentially lead to the system operating inefficiently and increase the risk of safety hazards, as this setting would not provide adequate pressure regulation in conjunction with the relief valve. This alignment is essential for safeguarding both the equipment and the people who operate it.
