Description
PR-59 Series
High Pressure Regulator
Designed for low and high pressures up to 4000 psig inlet the PR-59 Series pressure reducing regulator controls high flows with its Cv flow coefficient of 1.2.
While primarily designed for use with gas streams the PR-59 can be used with any liquid systems that are compatible with the seals. A large size piston sensor gives good sensitivity of control even at low outlet pressures and a balanced poppet design assures exceptional regulator accuracy.
