PR-56 Series
High Pressure Brass Regulator (6,000 psig Inlet)

To meet the demands for the safe reduction of
inlet pressures up to 6,000 psig, GO Regulator has
designed the PR-56 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 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.
