Hydraulic Cap

Hydraulic port terminator with zero flow


Hydraulic Elements


The Hydraulic Cap block represents a hydraulic plug, that is, a hydraulic port with zero flow through it. Physical network block diagrams do not allow unconnected conserving ports. Use this block to terminate hydraulic ports on other blocks that you want to cap.

You can also use this block to set the initial gauge pressure at a node.

The Variables tab lets you set the priority and initial target value for the Pressure (gauge) variable prior to simulation. For more information, see Set Priority and Initial Target for Block Variables.


The block has one hydraulic conserving port.

Introduced in R2012b
