The Bosch Rexroth Z2S16-1-5X (R900328797) is a high-performance industrial hydraulic sandwich plate valve designed for reliable blocking of oil flow at selected ports. This direct-actuated seat valve features a spool symbol A A, B B and allows for free flow in the direction from A to A or B to B, with the opposite direction being blocked. The valve is mechanically actuated and offers precise control, even during extended periods of inactivity. Incorporating a preopening feature, the Z2S16-1-5X ensures damped decompression of pressurized fluid to avoid potential switching shocks. Its two-stage setup with an increased control open ratio ensures secure unloading even under low pilot pressure conditions. This makes it particularly suitable for applications requiring controlled motion and reliable performance. The valve's design includes NBR seals and is compatible with hydraulic fluids such as HL, HLP, HLPD, HVLP, HVLPD, and HFC. It has been engineered for easy integration into hydraulic systems with its sandwich plate design conforming to ISO standards for porting patterns. The Z2S16-1-5X can be used for vertical stacking configurations and comes with various cracking pressures options. Additionally, it features a corrosion-protected design that enhances its durability in harsh environments. Its size corresponds to component series X standards, ensuring compatibility with a wide range of hydraulic systems. The maximum operating pressure and flow capacity are designed to meet demanding industrial requirements while maintaining efficiency and reliability in system operations. With individual check valve installation sets available, the Z2S16-1-5X provides flexibility for customization according to specific application needs. Whether it's used in manufacturing equipment or mobile machinery, this Bosch Rexroth hydraulic valve stands out as a robust solution for controlling fluid dynamics in sophisticated hydraulic circuits.
Size 16, A1 → A2, B1 → B2, mechanically actuated
Industrial hydraulic valve in a high performance range. Reliable blocking of the oil flow at selected ports.
Unpacked Weight: 6.86 kg
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 16 ‒…

Important information on hydraulic fluids: There may be limitations regarding the technical valve data (temperature, pressure range, life cycle, maintenance intervals, etc.). The ignition temperature of the hydraulic fluid used must be 50 K higher than the maximum surface temperature. Flame-resistant - containing water: Maximum pressure differential 210 bar, otherwise, increased cavitation erosion Life cycle as compared to operation with mineral oil HL, HLP 30 … 100%. Maximum hydraulic fluid temperature 60 °C Bio-degradable and flame-resistant – containing water: If this hydraulic fluid is used, small amounts of dissolved zinc may get into the hydraulic system. |

Notice:
Selection of optimal sealing material (see "Type code") also depends on the type of hydraulic fluid used.
