L’olio può fluire dall’alimentazione al cilindro. Il ritorno dal cilindro rimane bloccato finché la pressione di pilotaggio non apre la valvola interessata. Il blocco può così chiudere entrambi i lati di un cilindro idraulico a doppio effetto.\u003c\/p\u003e\u003cp\u003eSi tratta di una funzione di blocco.
