Barksdale Series S20517 Stainless Steel Pressure Regulator
BRAND : Barksdale
Barksdale's pressure regulators are sensitive pressure-control devices used to maintain a pre-determined pressure in a hydraulic circuit. The Stainless Steel Regulators offer corrosive-resistant, 316 stainless steel, units with SAE J518-2 code 62 flanges, which are standard with this series. Code 62 flanges are industry proven leak-free connections suited for higher pressure that offer ease of installation.
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.
