TECHNICAL FEATURES
Leakage listed in technical data is for each path.
Pressure at port 6 directly opposes port 1.
Hardened spool and sleeve provide consistent and low spool leakage rates and excellent wear characteristics.
Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge
machining variations.
