Question by: Ralph T on Jan 11, 2026, 8:31 AM

reckon this'll work alright with a hydraulic setup that runs pretty constant? Need somethin' that can hold up.

These flow control valves are indeed designed for use in hydraulic systems. The body is made of steel for durability, and the internal parts are made from stainless steel, Teflon, and Viton for longevity.
