Shuttle Valves Technical Information
Application Notes
There are two types of shuttle valves -- load shuttle valves and hot oil shuttle valves.OVERVIEW
Shuttle valves
LOAD SHUTTLE VALVE
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

Shuttle Valves Technical Information
Application Notes
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.
A common application for a hot oil
shuttle is diverting uid from the
low pressure side of a closed-circuit
hydrostatic loop for cooling and/or
ltering.
