Commercial Safety Valve, 15PSI, 1" | Mr. Steam
Commercial Safety Valve, 15PSI, 1" | Mr. Steam

The Mr.Steam Commercial Safety Valve 15PSI 1″ is a critical pressure-relief component engineered for large-capacity CU and C Series steam bath generators, including the CU4500/C4500 platform. Manufactured to discharge steam the moment system pressure exceeds 15 PSI automatically, it protects the pressure vessel, heating elements, and surrounding equipment from the risks of overpressure in high-demand commercial installations. Built for continuous-duty environments like health clubs, hotels, and day spas, this valve is designed to meet recognized ASME safety standards and deliver dependable, repeatable performance session after session. Its robust housing and 1″ connection are sized for the higher steam volumes generated by large commercial units, ensuring a secure, code-compliant fit without modification. Lightweight yet durable, it installs cleanly into existing plumbing as a direct OEM replacement, giving facility operators confidence that pressure protection meets the same rigorous standard as the original equipment.

  • Automatic Overpressure Relief – Activates precisely at 15 PSIG to vent excess steam pressure, protecting the pressure vessel and heating elements from damage in high-cycle commercial operation.
  • Commercial-Grade 1" Sizing – Sized for the larger steam volumes of CU2000–CU4500 series generators, ensuring proper flow capacity where a smaller residential valve would be inadequate.
  • ASME-Aligned Safety Design – Built to align with the pressure-relief standards referenced throughout Mr.Steam's CU Series documentation, supporting code-compliant commercial installations.
  • Direct OEM Fit – Matches the original factory specification for CU/C4500-class generators, avoiding adapters or modifications during replacement.
  • Continuous-Duty Reliability – Designed to withstand the demands of daily use in health clubs, hotels, and day spas where generators run for extended sessions across multiple rooms.
  • MPN: 99141
