DIRECTIONAL VALVES
LS10-50 Load Shuttle Network
DESCRIPTION
A cartridge-style check valve network for use in hydraulic load-sense circuits.
OPERATION
The LS10-50 will compare pressures from four circuits to provide a pressure signal
from the highest pressure circuit, while blocking the other circuits.
The valve will allow fl ow from the highest pressure port (
➄, ➃, ➂ or ➁) to port ➀.
FEATURES
• Hardened seat for long life and low leakage.
