1 Piston rod end (fixture
attachment end) An internal thread is provided for mounting load cells, swivels,
interface fixtures, or other components.
2 Porting High-pressure hydraulic fluid is ported into the end cap through
the retraction port (item 2A) or the extension port (item 2B).
Hydraulic fluid flow is regulated by a servovalve. As hydraulic
pressure is applied to one port, the other port is opened to a return
line, resulting in piston rod movement.
