The Bosch Rexroth Z2S6A1-6X (R900347498) is a high-performance, mechanically actuated industrial hydraulic valve designed for reliable operation and efficient flow control within hydraulic systems. This direct-actuated seat valve features a spool symbol A ↔ A, indicating its capability for bidirectional flow blocking, which is essential for applications requiring controlled movement or positioning. With a cracking pressure of 0 bar and the ability to accommodate a maximum pressure of up to 315 bar, this valve ensures secure operation under high-pressure conditions. The Z2S6A1-6X valve boasts a CETOP D03 size and conforms to NFPA T3.5.1 R2-2002 D03 and ISO 4401 porting patterns, ensuring compatibility with standardized mounting surfaces and simplifying installation in sandwich plate configurations. The connection diagram provided adheres to these standards, facilitating ease of integration into existing hydraulic systems. Equipped with NBR seals, the Z2S6A1-6X is suitable for use with various hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, and HFC types. Its robust design includes preopening features that allow for damped decompression, mitigating potential switching shocks that could otherwise lead to wear or noise generation in the system. This versatile sandwich plate valve comes with six ports and one switching position. It has a maximum flow capacity that ensures sufficient fluid transfer rates for various industrial applications. The mechanical actuation type of the Z2S6A1-6X allows for precise control over the flow paths within the hydraulic circuit. With its compact weight of just 0.9 kg (approximate), this Bosch Rexroth valve can be easily incorporated into vertical stackings without adding significant bulk or complexity to the system layout. Additional options such as varying cracking pressures and check valve installation sets are available upon request to tailor the product to specific operational requirements. Special versions can also be produced according to customer needs.

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.
