Pressure Reducing Valve | Mr. Steam

The Pressure Reducing Valve is engineered to lower and stabilize incoming water pressure as it enters Mr.Steam's MS and Steam@Home series residential steambath generators, maintaining the recommended 15-20 PSI inlet pressure the generator needs to operate safely and efficiently. Featuring a balanced piston design, an internal thermal expansion by-pass, and an integral stainless steel strainer, this valve delivers precise, consistent downstream pressure control even as supply conditions fluctuate. Its corrosion-resistant, sealed bronze body and bonnet, paired with an all-stainless-steel spring, are built to withstand the sustained heat and moisture of steam generator operation, rated for supply pressure up to 300 PSIG and a temperature range of 33°F to 180°F. Manufactured in the USA and factory tested, this valve is backed by a 2-year limited warranty, giving homeowners confidence in its long-term reliability. Straightforward to install with a standard 1/2" NPT connection, it protects the generator's internal components from pressure-related stress and helps preserve consistent, safe steam performance session after session.
