Filling Valves
Locking and Shuttle Valves
Filling valves from Bosch Rexroth connect the cylinder chamber to a reservoir tank on presses and large cylinders, in order to replenish large oil volumes during the rapid stroke. During the working stroke they close and enable pressure build-up in the cylinder.
The ZSF series is represented in the corresponding nominal size. The type code denotes nominal size and version.
Filling valves are used in hydraulic presses and systems with large cylinder volumes to draw oil pressureless from a reservoir tank during the fast closing stroke. In the subsequent working stroke they block so that the full pressing pressure can be built up.
