Blocking valves Series VBO – VBU
Unidirectional valves (VBU) and bidirectional valves (VBO)
Ports G1/8, G1/4, G3/8 and G1/2
Tube diameter: 6, 8, 10, 12 mm
Ports G1/8, G1/4, G3/8 and G1/2
Tube diameter: 6, 8, 10, 12 mm
These unidirectional and bidirectional blocking valves have been realised in order to enable mounting directly on cylinders.
They can be used as high flow valves for blows, cleaning of pieces, filling of volumes.
For these applications it is suggested to connect the supply to port 2 (having the mail thread).

These valves can be mounted directly also on distribution and fluid control blocks.
