Bosch Rexroth Z2S6B1-64 Block Valve

Bosch Rexroth Z2S6B1-64 is a pilot-operated check valve in the Z2S6 family, designed for installation in hydraulic valve blocks and sandwich plates. It provides one-way flow control to prevent backflow, protecting pumps and actuators and helping maintain system pressure when lines are de-energized. As a compact cartridge-style valve element, Z2S6B1-64 fits into Rexroth Z2S6 block assemblies and works with the corresponding sandwich-plate hardware to form modular hydraulic circuits. The model designation 64 identifies a variant within the Z2S6B1 family with interface characteristics defined by Rexroth. Typical applications include industrial hydraulic circuits where space is at a premium and reliable backflow protection is required.
