Victor Professional Single Stage SR 450, High Capacity, D (125 PSIG), Oxygen, 540, 9/16-18 UNF (M)

Recommended for applications where slight delivery pressure increases (due to decreasing cylinder pressures) would not affect the performance characteristics of the work or test results. The SR450 regulators are designed for medium to high capacity.

Recommended for applications that require a constant delivery pressure over a range of decreasing inlet pressures. This precise two stage regulation provides superior operating characteristics for applications where change in delivery pressure would affect performance characteristics of work or test results.
