The check pilotable valve allows the free flux of the oil in one direction, while it is prevented from the transit in the opposite direction till the valve is opened sending pressure to the piloting opening.

Normally provided with a pre-opening system that allows an initial decompression before the total flowing, the valve results particularly appropriate for the long maintenance of the pressure in starters or other circuits.

Valves of the series DCZ guarantee an optimal endurance till pressures of 400 bar.

In the storehouse they are available in three models bearing respectively 70, 110 e 170 Lt/min.
