Open the catalog to page 1Quick Reference Cartridge Valves Technical Information Shuttle Valves Application Notes OVERVIEW There are two types of shuttle valves -- load shuttle valves and hot oil shuttle valves. Shuttle valves Shuttle valves Application notes 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 Load shuttle valve Bi-directional motor...
Open the catalog to page 2Quick Reference Cartridge Valves Technical Information Shuttle Valves Application Notes Hot oil shuttles are spool-type valves that use internal piloting at 2 and 4 to direct oil from the lower of the two input pressures to the outlet at 3. Closed-circuit hydrostatic loop A common application for a hot oil shuttle is diverting fluid from the low pressure side of a closed-circuit hydrostatic loop for cooling and/or filtering.
