PR-50 Series

High Pressure Regulator

The PR-50 Series pressure regulator was designed to meet the demands for outlet pressures up to 2000 psig while maintaining superior corrosion protection.

For reliability in operation, this precision regulator features a stainless steel body which affords maximum  corrosion resistance coupled with the ultimate in safety. 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.
