The Bosch Rexroth Z2S6-1-6X/V (R900347504) is a mechanically actuated industrial hydraulic valve designed for reliable blocking of oil flow in hydraulic systems. This direct-actuated seat valve features a spool symbol A A, B B, indicating its capability to control flow in specific pathways. With a maximum pressure rating and the ability to accommodate a max flow rate, this valve is built for high-performance applications. The Z2S6-1-6X/V valve is part of Bosch Rexroth's product group ID and showcases a number of ports for versatile connectivity. Its mechanical actuation ensures precise control over the hydraulic circuit. The sandwich plate design allows for easy integration into various systems with connection diagrams compliant with NFPA T.. R D SizeCETOP D and ISO standards. Equipped with FKM seals, this valve is compatible with an array of hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR. Its robust construction ensures that it can maintain leakage-free blocking at one or two actuator ports even during extended periods of non-use. One notable feature of the Z2S6-1-6X/V is its preopening function which allows for damped decompression to avoid potential switching shocks that could otherwise cause premature wear or noise in the system. This two-stage setup ensures secure unloading even at low pilot pressures. The Bosch Rexroth Z2S6-1-6X/V valve also boasts flexibility with various cracking pressures available upon request and optional check valve installation sets. Its size and component series X specifications ensure it can handle up to a maximum operating pressure of bar and a maximum flow rate of l/min efficiently. In summary, the Bosch Rexroth Z2S6-1-6X/V (R900347504) sandwich plate valve offers high performance for hydraulic systems requiring precise flow control and reliable operation across various industrial applications.

CHECK VALVE SANDWICH PLATE Z2S6-1-6X/V

Size 6, A1 → A2, B1 → B2, mechanically actuated

Industrial hydraulic valve in a high performance range. Reliable blocking of the oil flow according to the hydraulic symbol

Unpacked Weight: 0.956801 kg

Sandwich plate valve for use in vertical stackings Porting pattern according to DIN 24340 form A (without locating hole) Porting pattern according to ISO 4401-03-02-0-05 (with locating hole) For the leakage-free blocking of one or two actuator ports, optional Various cracking pressures, optional (see ordering codes) With pre-opening, optional Check valve installation sets available individually Special versions on request

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.
