Industrial Regulators

BACK PRESSURE REGULATORS

MODEL 1164

MODEL 123 With five body materials and twenty-three trim material combinations, the Model 123 is compatible with most fluids. It can handle a wide range of flow and pressure settings to match nearly any back- pressure application up to a 2" line size. The regulator offers four composition seat materials and controlled compression with metal-to-metal back-up for long life and trouble-free operation.
