GRANIT Z80 Monoblock Hydraulic Distributor | 1x Double Acting | 80 l/min | 250 bar

The GRANIT 87000940 hydraulic distributor from the Z80 series is a 4/3 way monoblock directional valve, suitable for controlling a double-acting cylinder. This valve is designed to handle a larger flow rate, up to 80 l/min. The center function is A-B closed with spring return, which implies a closed center system where pressure is blocked in the neutral position. The valve is made of cast iron and is suitable for a nominal pressure of 250 bar.
