VP60 Analogue / IO-Link
Our policy is one of continued research and development. We therefore reserve the right
to amend, without notice, the specifications given in this document.
4. Basic function
The VP60 is a 5/3-way proportional valve of nominal size 8.
The flow-optimised, metal-seated 5/3-way spool is adjusted as quickly as possible to the position corresponding to the
setpoint by means of a moving coil and position sensor via a µP control loop.
In the production process, a setpoint / setpoint travel map is determined for each VP60 in such a way that a linear relationship
between setpoint and flow results under constant pressure conditions. Device-specific manufacturing tolerances are
compensated for by this procedure. The result is an idealised V-characteristic in the ratio of input setpoint to pneumatic flow.
However, the sensitively adjustable, proportional zero-cut characteristic is maintained in any case. When de-energised or in
the event of faults (see valve operating states), a spring presses the spool into the preferred position. The low-loss, digital
electronics are integrated in the valve.
There are no user-serviceable parts in the valve assembly.
The VP60 represents a bi-directional, linearized variable throttle and enables, for example, the stepless, reversible speed
control of double-acting cylinders or reversible pneumatic motors.
The VP60 represents a bi-directional, linearized variable throttle. Proportional to the input signal, the flow can be varied
continuously between negative and positive maximum values. In the middle position, all ports are blocked. Setpoints above the
middle open the passages 1 to 2 and 4 to 5. Setpoints below the middle open the paths 1 to 4 and 2 to 3. The latter are de-
energized or, in the event of a fault, spring-loaded fully open. In the delivery state, the valve is set to mode (5/3-way).
