Abstract

Digital hydraulics is a key part of the continuing applicability
of fluid power in the modern world. In order to realize the
potential of digital hydraulic circuits, valves which are able to
switch at high frequencies whilst retaining high flows are first
required. This paper details the development of a valve which
is capable of switching in 0.5ms whilst providing a flow rate
of over 50L/min at a 10bar pressure drop. Unlike most of the
other valves currently in development, position control is used
as opposed to the more common bang-bang actuation. This has
obvious benefits for valve robustness and offers the possibility
of a hybrid control approach which utilizes both throttling and
switching control. This paper will detail the design and empirical
testing of the valve and benchmark it against published and
commercial valves before proceeding to discuss the challenges
present in developing the valve further.
