Are pressure-reducing valves necessary for functionality in all boiler systems?

Pressure-reducing valves are not universally required for all boiler systems because some systems are designed to operate effectively without them. In specific applications, a boiler may be engineered to handle the pressure generated internally without the need for external regulation. For instance, certain high-pressure steam boilers contrast with low-pressure hot water systems, where pressure control may not be as critical. This flexibility in design means that there are conditions under which a boiler can operate safely and efficiently without the intervention of a pressure-reducing valve.

In addition, the necessity of these valves often depends on the overall system design and installation conditions, such as existing pressure levels in the supply lines and the specific requirements of the boiler model being used.
