CONTROL
Series VBO - VBU
blocking valves
Unidirectional valves (VBU) and bidirectional valves (VBO)
Ports G1/8, G1/4, G3/8 and G1/2
These unidirectional and bidirectional
blocking valves have been realised 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.
These valves can be mounted directly
also on distribution and fluid control
blocks.
