Unidirectional ball valves
The VUS series’ valves are unidirectional valves (or check valves). They allow so the flow pass free to them in a direction while, thank to the closing of a ball, the flow is interrupted in the opposite way.
The sealing of the closed valve, is granted thanks to a ball. Externally, a gasket avoid leakages through the threads.
The check valves VUS series are available with the sizes BSPP 1/4”, 3/8”, 1/2″.
Thanks to their compact dimensions, the employement of the check valves UVS is specially recommended in the design of hydraulic integrated manifolds.
The protection against the corrosion of the external components is granted thanks to the manganese phosphating treatment.
