PR-57 Series
High Pressure Corrosion-resistant Regulator (10,000 psig Inlet)
To meet the demands for the safe reduction of
inlet pressures up to 10,000 psig, GO Regulator has
designed the PR-57 Series regulator. This precision
regulator features a piston sensing design which
provides the operator with low adjusting torque requirements when setting the outlet pressure. The body is constructed from 316L stainless steel, providing the ultimate in safety and corrosion resistance. The optional self-relieving feature provides an additional level in operational ease, as it allows for trapped downstream pressure to be safely vented to atmosphere through the bonnet.
