SCS, VNR, VSC, VSO
Automatic valves are defined as those valves which change their state simply as a result of compressed air being present or absent at their inlets.

VBO-VBU
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.
