The Rexroth Z1S6A50-4X\/V (material no. R901086075) is a genuine Bosch Rexroth check valve: size 6, A1 \u2192 A2, with mechanical actuation.<\/p>\n
A pilot-operated check valve lets oil flow freely in one direction and holds the load in the other until the pilot pressure opens it, so cylinders do not drift when the directional valve is in neutral.<\/p>\n
