GRANIT Z80 Monoblock Hydraulic Distributor | 1x Double Acting (A-B-T Connected) | 80 l/min

The GRANIT 87001348 hydraulic distributor from the Z80 series is a 4/3 way monoblock directional valve, suitable for controlling a double-acting cylinder. The center function is A-B-T connected (open center) with spring return. This means that in the neutral position (center), the pump flow (P) is directed directly to the tank (T), allowing free outflow and reducing thermal load on the system. It is ideal for open-center hydraulic circuits with a flow rate of 80 l/min and a nominal pressure of 250 bar.
