The Bosch Rexroth Z2S10A1-3X/VXY (R900505152) is a highly reliable and efficient sandwich plate valve designed for vertical stack applications. This isolator valve type ZS is adept at providing leak-free blocking of one or two actuator ports, even during extended periods of inactivity, ensuring stable and secure operations. The valve allows free flow from A to A or B to B, while blocking the opposite direction. It features a control spool that can be moved to open a ball seat valve, allowing hydraulic fluid to flow freely when necessary.
Equipped with preopening as standard, the Z2S10A1-3X/VXY ensures damped decompression of pressurized liquid, thereby minimizing potential switching shocks that could otherwise cause wear on components or generate noise. The two-stage setup with increased control open ratio allows for secure unloading even at low pilot pressures. If a configuration without preopening is required, it is available as an option.
The design conforms to ISO standards for porting patterns and includes various cracking pressures to suit different application needs. Additionally, check valve installation sets are available separately for this model. The corrosion-protected construction of the Z2S10A1-3X/VXY enhances its durability and longevity in harsh environments.
This particular model boasts a component series X, which can withstand a maximum operating pressure of up to several hundred bar and accommodate maximum flow rates in liters per minute. Users should be aware that valves without preopening may cause sudden unloading of pressure which can result in switching shocks; hence the standard inclusion of preopening in this model mitigates such risks effectively.

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.
