TECHNICAL FEATURES

Different pilot control port options are available. See Option Selection for details.

All ports will accept 5000 psi (350 bar) including the pilot control port.

Hardened spool and sleeve provide consistent operation, low spool leakage rates and superior wear characteristics.

The minimum pilot pressure required to operate the valve is determined by the following formula: pilot pressure = 85 psi + pressure @ Port 1 times .023. This results

in a pilot pressure range of 85 to 200 psi. In metric; pilot pressure = 6 bar + pressure @ Port 1 times 0,023. This results in a pilot pressure of 6 to 14 bar.

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.
