Cla-Val 90G-21 (globe) and 90A-21 (angle) Pressure Reducing Valves automatically reduce a higher inlet pressure to a steady lower outlet pressure regardless of changing flow rate and/or varying inlet pressure. The valves pilot control system is very sensitive to slight downstream pressure fluctuations, and will automatically open or close to maintain the desired pressure setting.

Advantages include:
  • Globe or Angle Pattern
  • Proven Reliable Design
  • Available in Cast Bronze, Ductile Iron and Cast Steel
  • Accurate Pressure Control
  • Grooved Ends (1 1/2” - 8”)
