Looks What’s  New  from Cla-Val Fire Products Division

  • 300# Ductile Iron
  • Grooved Ends

For many years Cla-Val 90-21 UL listed pressure reducing valves were listed in ductile iron 150# flanged (rated to 175 psi) and 300# flanged cast steel (rated to 300 psi). The existing valves are still available but NOW the ductile iron valve is listed with 300# flanges (rated to 300 psi). In addition the Model 90-21 is NOW listed with grooved ends (rated to 300 psi) globe pattern sizes 1 1/2” - 6” and angle pattern sized 2” - 4”. The NEW grooved end design allows easier installation therefore cost are reduced.
