Digital simplicity: World first Festo Motion Terminal VTEM – Subject to change – 2017/11
Revolutionary: one valve technology for a huge range of functions
The new valve technology of the Festo Motion Terminal can be used for a wide range of products, functions
and complete solution packages. The only prerequisite is a valve design with multiple degrees of freedom for
actuation, as well as integrated data acquisition and processing suitable for a cyber-physical system. The
reduction to just 1 valve variant provides both system builders and operators with huge economic benefits.
• Four 2/2-way valves
(diaphragm poppet valves)
are connected in series to
form a full bridge
• Each diaphragm poppet valve
(grey) is proportionally piloted
and controlled by two piezo
valves (blue)
• Sensors monitor the stroke
of each poppet valve, while
pressure sensors monitor
the pressure at ports 2 and 4.
All four pilot cartridges
(blue) form a total of eight
proportionally controlled
2/2-way valves.Thanks to
the integrated sensors and
proportional control, which
allows the valves to be
pressurised and exhausted
independently, this single
valve technology can now
be used to execute a wide
range of conventional valve
functions and full system
solutions, such as Soft Stop
(available Q3/2018).
1 valve variant: a single valve
replaces over 50 individual
components
The bridge circuit in the valve
of the Festo Motion Terminal is
an innovative valve system that
is based on the basic elements
of pneumatic valve functions.
