1 pressure regulatorsPR-7 SeriesUltra High Flow Adjustable pressure reducing RegulatorThe PR-7 Series has been designed for those applications using high gas fl ow rates while still requiring a compact package. In addition, this unit will handle hydrogen fl ows up to 1000 liters per minute with none of the resonance problems typical with many regulators attempting such an designed for gas fl ow applications with low inlet pressures and low diff erential 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 fl ow requirements, this valve is very suitable as a primary pressure supply to other pressure regulators located & Specifi cations Minimal droop with large fl ow increased No resonance with large hydrogen fl ows 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.
