Ramp Test
The Ramp Test page allow you to adjust settings and run a ramp test.
The ramp test is a powerful tool for bench testing valves in a shop or installed valves that
are not in service and can be fully or partially stroked. By ramping the valve with a known
input and monitoring the response, changes over time can be noted and used to pinpoint
developing or existing problems.
CAUTION: During a test the valve will not respond to control signals and movement of the
valve stem will occur.
