GRANIT Z80 Monoblock Hydraulic Distributor | 1x Double Acting | 80 l/min | In-Line Pressure

The GRANIT 87001373 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 closed with spring return, which implies a closed center system. This valve is prepared for series pressure continuation, a function that allows other distributors to be connected in series in the hydraulic circuit. It is important to note that, despite being foreseen, the series pressure continuation is not installed as standard and must be fitted separately. The valve is made of cast iron and is suitable for a nominal pressure of 250 bar and a maximum flow rate of 80 l/min.
