This valve is a 4-way, 3 position, proportional directional valve. Work ports 2 and 4 are drained to 5 in the center
position and port 3 is closed. Pilot pressure at port 1 opposes the spring and creates a variable metering orifice
between ports 3 and 4 that is proportional to the pressure at 1. Piloting 6 opens 3 to 2. The force balance of the
flow forces, spring and pilot pressure results in a degree of partial self compensation as the load pressure changes.
Pressure at ports 1 and 6 directly oppose each other.

TECHNICAL FEATURES
Pilot ports 1 and 6 will accept 5000 psi (350 bar), however, pressures over 500 psi (35 bar) do not increase flow since at this point the spool will be fully shifted.
The valve exhibits a degree of self compensation. If more precise regulation of flow is required, then a separate compensator should be considered. This may be
achieved by the use of a bypass compensator, model LR*C-XHN, or a restrictive compensator, model LP*C-XHN.
Pressure at ports 1 and 6 directly oppose each other.
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.
