4-Way 3-Position Valve Parameterization

R2026b

This example shows how to parameterize and test a 4-way 3-position valve with a test harness. A plotting script compares the output flow between the block and data to verify the test harness.

Model

The following figure shows the 4-way 3-position valve test harness. The Pressure Source (IL) blocks and Ramp blocks create pressure boundaries for the directional control valve. A Constant block provides the spool displacement.
