The PR7 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 and 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, PTFE, PEEK, or Kalrez
Stainless steel cap
Cv flow coefficient = 1.10 (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 to 10 PSIG, 0 to 25 PSIG, 0 to 50 PSIG, 0 to 100 PSIG, 0 to 250 PSIG, or 0 to 500 PSIG
