The Bosch Rexroth Z2FS16-8-3X/S2 (R900457256) is a high-performance industrial hydraulic valve designed for efficient flow regulation within hydraulic systems. This throttle check valve, with its sandwich plate design, is engineered to limit the flow to one or two actuator ports, ensuring precise control over the movement of hydraulic actuators. The valve features two symmetrically arranged throttle check valves that utilize adjustable throttle spools to restrict flow in one direction while permitting free return flow in the opposite direction.
This particular model is equipped with a spindle that has an internal hexagon for direct actuation, allowing for accurate and easy adjustment of the throttling point. The spool symbol configurations available are A A, B B or A A, B B, mechanically actuated to suit various application requirements. With a maximum pressure capacity and multiple ports, this valve can handle demanding operational conditions.
The Z2FS16-8-3X/S2 is designed for sandwich plate mounting and adheres to NFPA T.. R D and ISO standards for porting patterns. It offers flexibility in terms of connection options and can be used for either meter-in or meter-out throttling applications. The size of the valve corresponds to CETOP D specifications, ensuring compatibility with standard subplates.
Constructed with NBR seals, it is compatible with a range of hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, and HFC types. The robust design guarantees reliable performance in controlling actuator speed by being installed between the directional valve and the subplate. Its maximum operating pressure reaches up to bar while it can accommodate a maximum flow rate of l/min. The product's weight adds to its stable installation without compromising ease of maintenance.
In summary, the Bosch Rexroth Z2FS16-8-3X/S2 offers exceptional control over fluid dynamics within industrial hydraulics systems through precise throttling capabilities and reliable construction suited for various mechanical applications.

The valve type Z2FS is a throttle check valve in sandwich plate design. It is used for the flow limitation of one or two actuator ports.
Two symmetrically arranged throttle check valves limit flows (by adjustable throttle spools) in one direction and allow free return flow in the opposite direction.
In case of supply throttling, the hydraulic fluid is directed through channel A➀ via throttling point (1) to actuator A➁. The throttle spool (2.1) can be axially adjusted via the spindle (3) for adjustment of the throttling point (1).
Simultaneously, the hydraulic fluid in channel A➀ is directed via the bore (4) to the piston side (5).
The active pressure and the spring force retain the throttle spool (2.1) in throttle position.
The hydraulic fluid return flow from actuator B➁ displaces the throttle spool (2.2) and enables the unobstructed flow as check valve. Depending on the version ("S" or "S2"), the throttling effect may occur in supply or discharge.
Flow limitation
For actuator velocity adjustment, the throttle check valve is installed between the directional valve and the subplate.
