The Bosch Rexroth Z2S6B3-6X/V (R900347512) is a high-performance, mechanically actuated industrial hydraulic sandwich plate valve designed for reliable blocking of oil flow in hydraulic systems. It features a spool symbol B B and is capable of handling a maximum pressure as denoted by its product group ID. This model has multiple ports and allows for mechanical actuation.
The Z2S6B3-6X/V is specifically engineered to enable the leak-free blocking of one or two actuator ports, maintaining its efficacy even during extended periods of non-operation. With a free flow from A to A or B to B and blocked flow in the opposite direction, this valve ensures directional control of hydraulic fluid within the system. The control spool and poppet design facilitate the movement and regulation of hydraulic fluid, with the added feature of preopening that aids in damping decompression, thus minimizing potential switching shocks.
This Bosch Rexroth valve is suitable for vertical stacking applications and conforms to DIN form A without locating hole and ISO with locating hole standards. It offers versatility with various optional cracking pressures and the availability of preopening features according to ordering codes. Additionally, check valve installation kits are available separately for this model.
The Z2S6B3-6X/V boasts compatibility with a range of hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR. The seals are made from FKM material ensuring durability under different operating conditions. Its design also includes specifications such as size component series X with a maximum operating pressure denoted in bar units and maximum flow measured in liters per minute. Special versions can be requested to meet specific requirements beyond standard offerings.

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.
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!
The length of the valve mounting screws of the sandwich plate valve must be selected according to the components mounted under and over the isolator valve.
Depending on the application, screw type and tightening torque must be adjusted to the circumstances.
Please ask Rexroth for screws with the required length.
