The Bosch Rexroth Z2S10A1-3X/V (R900407440) is a mechanically actuated industrial hydraulic valve designed for high-performance applications, ensuring reliable, leakage-free blocking of selected ports. This direct-actuated seat valve is adept at controlling pilot control valves with a spool symbol A A. It features a maximum pressure capacity and an electrical connection description that aligns with its robust product group ID.
This valve boasts numerous ports and leverages mechanical actuation, which underscores its versatility in various hydraulic systems. With its specified size, the Z2S10A1-3X/V can handle a significant max flow rate and offers different types of connections including interim assembly options. The connection diagram adheres to ISO standards, guaranteeing compatibility with a wide range of equipment.
Weighing in at an efficient mass, the valve is equipped with FKM seals and is compatible with various hydraulic fluids such as HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, HFDR. Its design as an isolator valve type ZS in sandwich plate configuration makes it ideal for applications requiring the leak-free blocking of one or two actuator ports even during extended periods of inactivity.
The Z2S10A1-3X/V facilitates free flow from A to A or B to B while ensuring blocked flow in the opposite direction. The presence of preopening features allows for damped decompression of pressurized liquid to avoid potential switching shocks. This two-stage setup with an increased control open ratio ensures that even low pilot pressures can be securely unloaded.
For systems without preopening features in this model range, users are advised about the potential for sudden unloading of pressure which may cause switching shocks that could result in premature wear on components and noise generation. The design also includes corrosion protection and comes with check valve installation sets available individually. It adheres to porting patterns according to ISO standards for seamless integration into vertical stacking configurations and offers various cracking pressures.

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.

Deviating from ISO 4401, port T is in this data sheet called TA, port T1 is called TB.
