PR-57 Series High Pressure Corrosion-Resistant R

Brand: GO Regulator

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.
