PNEUMATIC DATA
Series VBO - VBU (Nickel Plated)
Pilot-Operated Check/Blocking Valves
Unidirectional (Pilot-Operated Check Valve)
and Bidirectional (Blocking Valve) 1/8”, 1/4”, 3/8” NPTF
Nominal diameters 5.5 - 8 - 11 mm
These valves have been designed to mount
directly into the cylinder ports.
The inner design of the blocking valves
Series VBO and VBU allows a very high
flow rate and reliable operation.
