Shuttle valves<br />

A load shuttle valve communicates<br />

the higher of two inlet pressures at<br />

1 and 3 to the outlet at 2. A steel<br />

ball is used to seal the lower pressure.<br />

Load shuttles have several common<br />

applications including:<br />

· Logic for load sensing circuits<br />

· Bi-directional motor brake release<br />
