Unidirectional check valves
The valves of the VU series are one-way check valves, they allow the oil to pass through in one direction and interrupted in the opposite direction.
Externally, a gasket prevents oil leaks through the threads. They are built in various sizes with threads starting from 1/8 BSPP (1/8 G) up to 3/4 BSPP (3/4 G). Thanks to their compact size, the use of the VU series built-in check valves is particularly suitable for the design of integrated hydraulic circuits.
Corrosion protection of the external components of the valve is ensured by manganese phosphating treatment.
