1

A miniature boiler is typically equipped with one safety valve. This is a crucial safety feature designed to prevent excessive pressure build-up within the boiler. The single safety valve is calibrated to open at a pre-determined pressure, allowing steam to escape safely and maintaining the operating pressure within safe limits. Having a single safety valve simplifies the design and operation of miniature boilers, which are often used in smaller applications or models. The use of more than one safety valve would generally be unnecessary and could complicate maintenance and operation, especially in smaller systems where space and resources are limited.
