The Bosch Rexroth Z2FS22-8-3X/SV (R900474580) is a high-performance industrial hydraulic valve designed for reliable throttling of flow to a set value. This direct actuated valve features a spool symbol for configurations A A, B B or A A, B B, and is mechanically actuated. With its maximum pressure sustainability and multiple ports, the Z2FS22-8-3X/SV is capable of handling a variety of hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR.
This sandwich plate valve comes with FKM seals and conforms to NFPA T.. R D SizeCETOP D and ISO connection diagrams. It has been engineered to allow for precise flow limitation of one or two actuator ports using two symmetrically arranged throttle check valves. These valves limit flows in one direction through adjustable throttle spools while permitting free return flow in the opposite direction.
The Z2FS22-8-3X/SV's construction allows for easy adjustment via an internal hexagon spindle. The design ensures that the hydraulic fluid is efficiently directed through the necessary channels and that the throttle spool can be axially adjusted to manage the throttling point effectively. This feature enables users to fine-tune actuator velocity as required.
With its corrosion-protected design and capability for either supply or discharge throttling, this Bosch Rexroth valve stands out as an essential component in various hydraulic systems. Its robust construction ensures longevity even in demanding environments. The valve is part of the X component series and can withstand a maximum operating pressure of bar while accommodating a maximum flow rate of l/min.

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.
