Industries

  • Research and development
  • Gas cabinets
  • High pressure gas systems
  • Injection molding
Features & Benefits
  • Ability to reduce high inlet pressures from 1 – 400 psig (0 to 27,6 bar) in one valve
  • Provides superior sensitivity in pressure regulation to the piston operated JRPL, and has a Cv that’s nearly 10x greater than the 0.2 Cv in the JR Series
  • Barstock construction guarantees material integrity and surface finish
  • High flow rate coupled with high rangeability reduces need for reduced trim sizes
  • Optimized internal volume
  • Soft seat material for ANSI Class VI shutoff
