Product overview

5.1

Functional principle

The valve unit consists of a 3/3-way proportional-pressure regulator and
two 2/2-way valves. The purpose of the 3/3-way proportional-pressure regulator
is to regulate the cylinder pressure and the cylinder position. The two 2/2-way
valves serve as non-return valves for shutting off the cylinder volume in the event
of an error (loss of voltage, fall in pressure, too high travel speed, etc.). For
increased safety requirements, the valve unit can be equipped with switching pos-
ition sensing for the non-return valves (VPCB-...-T22-M).

1. Make sure there is sufficient space for the connecting cable and tubing con-
nections.
Ä This will prevent kinks from forming in the connecting cables and the
2. Place the valve as close to the consumer as possible.
Ä This leads to better control response.
3. Attach the valve using the 4 screw holes M5 (10 mm deep) under the valve or
on the valve side with the pneumatic connections (1) and (3). Tightening
