Pressure Reducing Valves (Internally Adjustable)

Pressure reducing hose valves and floor control valves are used to control the pressure of flowing water in standpipe and sprinkler systems.  NFPA requires pressure reducing valves where the inlet pressure exceeds 175 PSI.  The field adjustability of these valves gives the installer/engineer the option to set the desired PSI rating themselves versus having the manufacturer do it.

Specifications: 
  • Field adjustable or set at the factory
  • U/L Listed
  • 400 PSI max operating pressure
  • Available in angle or in-line configurations
  • Grooved and threaded options
  • Material:  Cast brass

  • Various components available: 

  1. Monitor switch adapter add-on (Suffix 'MSA')
