GRANIT Z80 Monoblock Hydraulic Distributor | 1x Double Acting | Detent | 80 l/min

The GRANIT 87001375 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 detent in position 1-0-2. This means the lever can be locked in all three main positions: both working positions (1 and 2) and the neutral position (0). In the neutral position, the pump flow (P) is directed to the tank (T). It is important to note that the detent is not installed as standard. The valve is suitable for a flow rate of 80 l/min and a nominal pressure of 250 bar.
