The PR-7 Series has been designed for those applications using high gas flow rates while still requiring a compact package. In addition, this unit will handle hydrogen flows up to 1000 liters per minute with none of the resonance problems typical with many regulators attempting such an application.

While designed for gas flow applications with low inlet pressures and low differential pressures, this valve has been constructed to withstand inlet pressures up to 3600 psig. With capability of holding outlet pressures closely with large changes of flow requirements, this valve is very suitable as a primary pressure supply to other pressure regulators located downstream.

Features & Specifications
  • Minimal droop with large flow increased
  • No resonance with large hydrogen flows
  • Stainless steel diaphragm
  • 316L stainless steel or brass construction (optional Hastelloy®, Monel®, or chrome-plated brass)
  • T-handle adjusting assembly for easier adjustment in the 250 and 500 psig ranges
  • Material of construction: brass, stainless steel, Viton®, Teflon®, PEEK™, or Kalrez®
  • Stainless steel cap
  • Cv flow coefficient = 1.1 (full Cv with 1/2" ported unit only)
  • Operating temperatures up to +250° F (+121° C)
  • Maximum inlet pressure of 3600 psig with PEEK™ seat
  • Inlet/outlet connections: 1/4", 3/8", or 1/2" FNPT
  • Outlet pressure ranges of: 0 - 10, 0 - 25, 0 - 50, 0 - 100, 0 - 250 & 0 - 500 psig
