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

Shuttle Valves Technical Information
Application Notes
HOT OIL SHUTTLE VALVE Hot oil shuttles are spool-type valves |
Closed-circuit hydrostatic loop |
|||||
|
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 fluid from the |
|
||||
|
low pressure side of a closed-circuit |
|
||||
|
hydrostatic loop for cooling and/or |
|
||||
|
filtering. |

Load Shuttle Valve - Normal Direction
CP124-1
OPERATION |
This valve senses the higher of the two |
|||
|
input pressures at ports 1 and 3 and |
|||
|
routes it to the output port 2. |
