GRANIT Z50 Monoblock Hydraulic Distributor | 1x DA (A-B-T Connected) | 40 l/min | 250 bar

The GRANIT 87001340 hydraulic distributor is a 4/3 way monoblock directional valve with a single lever. It is designed to control a double-acting cylinder and is characterized by its central (neutral) position where all ports (A, B, P, T) are connected to each other (A-B-T connected). This allows the fluid to flow freely between the reservoir and the pump when the valve is not actuated, reducing the load on the pump. The lever returns to the neutral position actuated by a spring. Made of cast iron, it is ideal for hydraulic systems requiring a nominal pressure of 250 bar and a maximum flow rate of 40 l/min.
