Directional

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.

• Nominal operating pressures for port 1 and port 6 should not exceed 500 psi (35 bar).
• 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.
