GRANIT Z50 Monoblock Hydraulic Distributor | 1x Double Acting | Float Position

The GRANIT 87001341 hydraulic distributor is a 4/3 way monoblock directional valve, ideal for controlling a double-acting cylinder, with the additional function of a position flottante with detent in position 3. In the float position, both A and B ports are connected to the tank (T), allowing the cylinder to move freely under an external force, an essential feature for applications like snowplows or agricultural attachments. The center is A-B closed and the lever spring returns to the neutral (center) position from positions 1 and 2. Made of cast iron, it withstands a nominal pressure of 250 bar and a maximum flow rate of 40 l/min.
