The Bosch Rexroth Z2S10-1-3X (R900407394) is a mechanically actuated industrial hydraulic valve designed for high-performance applications. This direct-actuated seat valve features a spool symbol A to A, B to B, ensuring reliable blocking of the oil flow at selected ports. It is particularly suitable for scenarios requiring leakage-free blocking of one or two actuator ports, even during extended periods of inactivity.
The Z2S10-1-3X valve offers a free flow in the direction from A to A or B to B, while blocking the flow in the opposite direction. This functionality is achieved through a control spool that moves to open the ball seat valve and displace the poppet off its seat, allowing hydraulic fluid to flow from port B to B. To ensure safe closure of the ball seat valve, the control spool must be hydraulically unloaded as indicated in the provided circuit examples.
This model includes preopening as a standard feature, which serves to dampen decompression and minimize potential switching shocks that could otherwise cause premature wear on components and noise issues. However, models without preopening are available as well and should be considered based on application specifics.
With its sandwich plate design, this isolator valve type ZS can be used in vertical stackings and conforms with ISO porting patterns for easy integration into various systems. It offers multiple cracking pressures and comes with an optional preopening feature. Check valve installation sets are also available individually for this corrosion-protected design.
Key specifications include a maximum operating pressure of bar and a maximum flow rate of l/min. The product group ID, number of ports, type of actuation (mechanical), size, type of connection (interim assembly), connection diagrams conforming to NFPA T.. R D Size CETOP D and ISO standards are also notable aspects of this model. The weight is . kg and it utilizes NBR seals compatible with several types of hydraulic fluids such as HL, HLP, HLPD, HVLP, HVLPD, and HFC.

The isolator valve type Z2S is a releasable check valve in sandwich plate design.
It is used for the leakage-free blocking of one or two actuator ports, also in case of longer standstill times.
In direction A① to A② or B① to B②, there is a free flow; in the opposite direction, the flow is blocked.
If, for example, there is a flow through the valve in direction A① to A②, the control spool (1) is moved in the direction of the B side, opens the ball seat valve (2) and then pushes the poppet (3) off its seat. Hydraulic fluid can now flow from B➁ to B➀.
In order to allow the ball seat valve (2) to be safely closed, the control spool (1) must be hydraulically unloaded (see circuit example).
Pre-opening
Due to the pre-opening, there is a damped decompression of the pressurized liquid. Thus, possible switching shocks are avoided. The two-stage set-up with an increased control open ratio means even low pilot pressure can be unloaded securely.Type Z2S 10 ‒… (with pre-opening)

Notice:
In valves without pre-opening, sudden unloading of pent-up pressure volume may occur. Resulting switching shocks may lead to premature wear on installed components, as well as noise formation.
Notice:
Deviating from ISO 4401, port T is in this data sheet called TA, port T1 is called TB.
