The Bosch Rexroth Z1S6A05-4X/V (R901086070) is a high-performance, mechanically actuated industrial hydraulic valve designed for reliable blocking of oil flow in selected ports. This direct-actuated seat valve features a spool symbol A A and is capable of operating at a maximum pressure as specified in its technical characteristics. It comes with an electrical connection description that aligns with industry standards.
The valve type ZS, part of this model code, is recognized for its direct operation in a sandwich plate design, facilitating leakage-free blocking in one direction while permitting free flow in the opposite direction. The stroke of the poppet within the valve is limited by a plastic socket, which also aids in the closing movement supported by an installed spring. This ensures that when there is no fluid flow, the spring maintains the poppet in a closed position.
This particular model can be utilized both as an angle valve and as a straight-through valve, with porting patterns conforming to ISO standards. It boasts exceptional leak-tightness due to its high-performance plastic poppet and corrosion-resistant design. For special hydraulic fluid requirements, external seal rings can be exchanged to accommodate various types such as HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR.
Additionally equipped with optional measuring ports and available as a throttle check valve upon request, the Bosch Rexroth Z1S6A05-4X/V valve's versatility extends to various one-channel and two-channel blocking functions. Its size and component series are designed for maximum operating pressure and flow rates as indicated by its specifications. The seals are made from FKM material for durability and performance.
Overall, this Bosch Rexroth hydraulic valve stands out for its adaptability to vertical stackings and ease of adjustment to different hydraulic fluids—making it an essential component for sophisticated hydraulic systems requiring precise control over fluid dynamics.

The valve type Z1S is a direct operated check valve in sandwich plate design.
It is used for the leakage-free blocking in one direction and allows for free flow in the opposite direction.
The stroke of the poppet (1) is limited by the plastic socket (2). The installed spring (3) supports the closing movement. When no fluid flows through the valve, the spring (3) keeps the poppet (1) in closed position.
In contrast to the straight-through valve (section 1), the angle valve (section 2) links or closes off up to three internal channels. Stop and sealing function are taken over by the plug screw (4).
Notice:
For all installation positions in which the blue plastic socket (2) is mounted at the plate side ➁, no additional seal ring may be used at this position!
At the component side ➀, the seal ring (5) (as usual) seals the assembly installed downstream.
The installed plastic socket (2) has a sealing function and may not be removed or damaged.
