The Bosch Rexroth Z1S6T30-4X/V (R901086059) is a mechanically actuated industrial hydraulic valve designed for high-performance applications that require reliable blocking of oil flow at selected ports. This direct operated check valve comes in a sandwich plate design, suitable for vertical stacking either as an angle valve or straight-through valve. The model features a spool symbol T T and is capable of handling a maximum pressure with various options for electrical connections.
This Bosch Rexroth valve boasts a number of ports and offers mechanical actuation. It is specifically designed to ensure leak-free blocking in one direction while permitting free flow in the opposite direction. The poppet's stroke is limited by a plastic socket, and an installed spring aids the closing movement, ensuring the poppet remains closed when there's no fluid flow.
The Z1S6T30-4X/V offers versatility with its porting pattern compliant with ISO standards, accommodating various one- and two-channel blocking functions. Its poppet is made from high-performance plastic, contributing to perfect leaktightness, while its corrosion-protected design extends the valve's lifespan. For adaptation to special hydraulic fluids, external seal rings can be exchanged easily.
Additionally, optional measuring ports are available, and it can be requested as a throttle check valve. With its size and component series X, it can handle maximum operating pressures up to bar and maximum flow rates of l/min. The robust construction and detailed engineering make this Bosch Rexroth valve an essential component for sophisticated hydraulic systems where precision and reliability are paramount.

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.
