These valves have been designed in order to
enable mounting directly on cylinders.
The inner design of the blocking valves Series
VBO and VBU allows a very high flow rate and
reliable operation.
Pilot-Operated Check/Blocking Valves
Series VBO - VBU - BSP/METRIC
*
in the event that lubricated air is used, it is recommended to use oil ISO VG32. Once applied, the lubrication should never be interrupted.
