  • Safety Valves

A safety valve is a valve mechanism for the automatic release of a substance from a boiler, pressure vessel, or other system when the pressure or temperature exceeds preset limits. It is part of a bigger set named pressure safety valves (PSV) or pressure relief valves (PRV). The other parts of the set are named relief valves, safety relief valves, pilot-operated safety relief valves, low pressure safety valves, vacuum pressure safety valves.

Safety Valve Specifications:

  • ASME NB/UV, CRN Coded & Non-Coded
  • Brass or Stainless Steel
  • 5 to 600 PSI / -250°F to 400°F
  • 1/8" to 1"

PSI Specification

If ordering online, at Step 4: Review Your Order, enter in the "Review Order Notes" box your PSI in increments of 5 according to the PSI range listed above. If ordering through customer service, be sure to let them know the PSI increment needed.
