Series 20597 1-1/2" Heavy-Duty Hydraulic Regulator

Brand: Barksdale

Barksdale's increased sensitivity regulator is a sensitive, pressure-control device used to maintain a pre-determined pressure in a hydraulic circuit.

This version offers better reaction time and better set point accuracy.

The regulated output pressure is controlled by manually adjusting the spring force to balance the hydraulic loading.

Design features ensure excellent accuracy, repeatability and high flow coefficients.
