Unidirectional poppet valves
They are used in all those circumstances where full flow in one direction and blockage in the opposite direction are required, they are built in various sizes with threads from 1/4 BSPP (1/4 G) to 1/2 BSPP (1/2 G).
These tapered poppet valves are useful where there are space problems, or to compact the hydraulic system.
The couplings are made of high resistance steel and protected externally from oxidation by a zinc treatment.
It is possible to request the valves with opening pressures different from the standard (0.5 bar), for example 3-4.5-6 bar.
