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

The GRANIT 87001374 hydraulic distributor from the Z80 series is a 4/3 way monoblock directional valve, suitable for controlling a single-acting cylinder. The spool function in the neutral position is A closed with spring return. The valve is prepared for series pressure continuation (closed system in center), a function that allows other distributors to be connected in series in the hydraulic circuit. It is important to note that the series pressure continuation is not installed as standard. 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.
