The Bosch Rexroth Z2S6A1-6X/V/62 (R901126655) is a high-performance industrial hydraulic valve designed for reliable operation in mechanically actuated applications. This direct-actuated spool valve, featuring a spool symbol A A, is specifically engineered to provide secure blocking of oil flow. It operates with a maximum pressure as specified by the product group ID and includes a number of ports suitable for various hydraulic circuit requirements. The Z2S6A1-6X/V/62 valve is characterized by its mechanical actuation and has been optimized for maximum flow rates.
The device is constructed as a sandwich plate valve, enabling it to be integrated into vertical stackings and ensuring compatibility with NFPA T.. R D Size CETOP D and ISO connection diagrams. It offers multiple switching positions and comes with FKM seals, making it suitable for use with a wide range of hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR.
This Bosch Rexroth isolator valve stands out due to its preopening feature which allows for damped decompression of pressurized liquid to avoid potential switching shocks that could otherwise lead to wear on components or noise issues. The two-stage setup ensures secure unloading even at low pilot pressures.
The Z2S6A1-6X/V/62 valve also offers versatility through optional features such as various cracking pressures and the availability of check valve installation sets. Its design complies with both DIN form A without locating hole and ISO with locating hole porting patterns. Customers can also inquire about special versions tailored to specific requirements. The size and component series along with its maximum operating pressure in bar and maximum flow rate in liters per minute are detailed in the ordering codes provided by Bosch Rexroth for this product.

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.
