TECHNICAL FEATURES
All ports will accept 5000 psi (350 bar), including the x and y pilot ports (port 1 and port 6).
Leakage listed in technical data is for each path, including pilot paths.
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.
