***Disclaimer: The following summary contains information gathered from various sources such as product descriptions, technical specifications and catalogs. While efforts have been made to provide accurate details, inaccuracies may occur. It is advised to verify all information by contacting Bosch Rexroth directly.***
The Bosch Rexroth Z2S16-1-5X/V (R900412459) is a high-performance industrial hydraulic valve designed for reliable, leakage-free blocking of selected ports. This seat valve is directly actuated and used to control a pilot control valve, featuring a preopening function to mitigate high switching loads. It is characterized by its spool symbol A A, B B, which indicates its flow directions for free and blocked flow respectively. The Z2S16-1-5X/V valve operates with a maximum pressure capacity and offers an electrical connection that aligns with specified product group standards. It has a specific number of ports and utilizes mechanical actuation. The size of this valve corresponds with the maximum flow it can handle, ensuring efficient operation within hydraulic systems. This model utilizes an interim assembly connection diagram compliant with ISO standards and features multiple switching positions. The weight of the valve is calibrated to maintain balance in system integration. It is designed with FKM seals compatible with a range of hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR. The Z2S16-1-5X/V serves as an isolator valve type ZS in a sandwich plate design suitable for vertical stackings. Its porting pattern adheres to ISO standards for consistent and secure installation. The valve offers various cracking pressures along with the convenience of preopening to avoid potential switching shocks due to damped decompression. For maintenance or modifications, check valve installation sets are available individually. Overall, this Bosch Rexroth hydraulic valve stands out for its corrosion protection design and versatile application in controlling fluid dynamics within complex hydraulic systems where precise flow regulation is critical.


Size 16, A1 → A2, B1 → B2, mechanically actuated

Industrial hydraulic valve in a high performance range. Reliable leakage-free blocking of selected ports.

Unpacked Weight: 6.91 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.

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.
1) Not recommended for corrosion-protected version "J3" (contains zinc)

Notice:

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