DIRECTIONAL VALVES

DESCRIPTION

A load-shuttling, screw-in, cartridge-style hydraulic check valve, for use in blocking

circuits where a priority of flow/direction is given to a higher pressure circuit over a

lower one.

OPERATION

The HLS06-B30 will allow flow from the higher pressure of port 1 or 3 to port 2.

The valve is commonly used to direct oil from the pressure side of a bidirectional

hydraulic motor to a pressure-released hydraulic brake. It can also be used as a load-

sense signaling valve.

FEATURES

• Rapid response to load direction changes.

• Higher flow capacity.

• Lower pressure drop.

• Reduced space claim and smaller hydraulic "footprint".

• All HyPerformance™ products are tested to the rigorous standards of NFPA

specification T2.6.1 to a verification level of 90% and an assurance of 99%.
