The Bosch Rexroth Z1S6C50-4X/V (R901086087) is a highly versatile direct operated check valve designed for seamless integration into hydraulic systems requiring leak-free blocking in one direction and free flow in the opposite. This sandwich plate valve is ideal for vertical stacking applications, functioning both as an angle valve and a straight-through valve. The model adheres to the ISO porting pattern standard, ensuring compatibility with a wide range of systems.
Equipped with a high-performance plastic poppet, the Z1S6C50-4X/V guarantees perfect leaktightness, critical for maintaining system integrity and performance. The included spring aids in the closing movement of the poppet and ensures that it remains closed when no fluid is flowing through the valve. Additionally, this model features a plastic socket that not only limits the stroke of the poppet but also serves as a seal when mounted on the plate side of installations; this unique feature negates the need for an additional seal ring at this position.
The corrosion-protected design of this check valve extends its service life even in harsh operating environments. For systems requiring customization, users can adjust the external seal rings to accommodate special hydraulic fluids. Furthermore, optional measuring ports are available for enhanced monitoring capabilities.
As an angle valve, it can link or close off up to three internal channels while providing stop and sealing functions via its plug screw. In contrast, as a straight-through valve section, it facilitates simple connections within hydraulic circuits.
For those needing throttle check capabilities, this functionality can be requested upon order. The Bosch Rexroth Z1S6C50-4X/V is designed to withstand maximum operating pressures up to bar levels and can handle flow rates measured in liters per minute (l/min), though specific values are dependent on component series and configurations chosen during purchase.

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.
