They are for comparison purposes only.

Shuttle Valves Catalog Application Notes There are two types of shuttle valves -- load shuttle valves and hot oil shuttle valves. LOAD SHUTTLE VALVE A load shuttle valve communicates the higher of two inlet pressures at 1 and 3 to the outlet at 2. A steel ball is used to seal the lower pressure. Load shuttles have several common applications including: · · Logic for load sensing circuits Bi-directional motor brake release valve Load sensing circuit SH - Shuttle Valves Catalog Application Notes Shuttle valves Load shuttle valve Bi-directional motor brake release valve
