Barksdale Control Products Hydraulic Pressure Regulator Model 20517

Barksdale's pressure regulators are sensitive, pressure-control devices used to maintain a pre-determined pressure in a hydraulic circuit. 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. Designed to provide years of trouble-free operation and virtually zero leakage, the Shear-Seal® design uses fluid pressure to maintain a leak-free metal-to-metal seal that improves with use. The shearing action between the rotor & pressure seal continually laps the mating surfaces and prevents contaminates from lodging between the sealing surfaces. The result is a valve that doesn’t wear out – but wears in over time, providing you superior control consistently through the entire life of the product.
