The PRG350 series of stainless
steel filter regulators are designed
to stand up to the harshest
environments while providing
highly accurate pressure regulation.
Proven 316 stainless steel housing
and filter assemblies along with
fluorocarbon elastomers make the
PRG350 compatible with sour
gas and adaptable to off shore
environments.
