GRANIT Z50 Monoblock Hydraulic Distributor | 1x Single Acting (EW) | 40 l/min | 250 bar

The GRANIT 87001342 hydraulic distributor is a 4/3 way monoblock directional valve, suitable for controlling a single-acting cylinder. The version indicates that, in the neutral position (center), port A is closed (A closed / spring return). Since this is a single-acting cylinder distributor, port B is not used. The valve has a closed center, stopping the main flow P in the neutral position. The lever spring-returns to the neutral position. Made of cast iron, it is suitable for a nominal pressure of 250 bar and a maximum flow rate of 40 l/min.
