[115] 4/3-way valve with pump bypass
The animations show the
switching of the 4/3-way valve into the three switching positions
and the corresponding cylinder movements. During the advance
stroke, movement can be halted by switching to the mid-
position.
As appropriate to the application in question, a circuit of this kind must be equipped with a brake valve to prevent damage to the installation when the valve is switched to the mid-position (see also topic 64).
