The Bosch Rexroth Z2FS10A5-3X/S2V (R900523578) is a high-performance industrial hydraulic valve designed for precise flow regulation within hydraulic systems. This throttle check valve, part of the ZFS series, is intended for sandwich plate installation and serves to limit the main or pilot flow to one or two actuator ports. Its construction allows for reliable throttling to a set value while enabling free return flow in the opposite direction. The Z2FS10A5-3X/S2V features a spindle with an internal hexagon and scale for accurate adjustments, and it operates with mechanical actuation. The spool symbol A A or A A indicates its specific configuration, which contributes to its functionality in various applications. The valve can withstand a maximum operating pressure as indicated by its product group ID and supports a maximum flow rate as specified in its detailed specifications. Equipped with FKM seals, the Z2FS10A5-3X/S2V is compatible with multiple types of hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR. It follows the porting pattern according to ISO standards and comes in size CETOP D. Additionally, it offers various adjustment types such as a lockable rotary knob with scale and corrosion-protected design for longevity in harsh environments. This valve is suitable for applications requiring precise actuator velocity adjustment through main flow limitation or switching time adjustment through pilot flow limitation. Whether installed between directional valves and subplates or between pilot control valves and main valves, the Bosch Rexroth Z2FS10A5-3X/S2V ensures efficient operation of hydraulic systems where controlled flow rates are critical.

THROTTLE CHECK VALVE Z2FS10A5-3X/S2V

Size 10; A1 → A2 or A2 → A1; mechanically actuated

Industrial hydraulic valve in a high performance range. Reliable throttling of the flow to setting value.

Unpacked Weight: 2.98 kg

Sandwich plate valve Porting pattern according to ISO 4401-05-04-0-05 For the main or pilot flow limitation of 2 actuator ports. 3 adjustment types:• Lockable rotary knob with scale• Spindle with internal hexagon and scale• Rotary knob with scale Meter-in or meter-out throttling Corrosion-protected design

The valve type Z2FS 10 is a throttle check valve in sandwich plate design. It is used for the main or pilot flow limitation of one or two actuator ports.

Two throttle check valves aligned symmetrically to each other limit flows in one direction and allow free return flow in the opposite direction.

In case of supply throttling, the hydraulic fluid is directed through channel A1 via throttling point (1) formed by the control edge (2) and the throttle spool (3.1) to actuator A2. The throttle spool (3.1) can be axially adjusted via the spindle (4) for adjustment of the throttling point (1).

Simultaneously, the hydraulic fluid in channel A1 is directed via the bore (5) to the piston side (6). The active pressure and the spring force retain the throttle spool (3.1) in throttle position.

The hydraulic fluid return flow from actuator B2 displaces the throttle spool (3.2) against the spring (7) and enables the unobstructed flow as check valve. Depending on the installation position, the throttling effect may occur in supply or discharge.

Main flow limitation

For actuator velocity adjustment (main flow limitation), the throttle check valve is installed between the directional valve and the subplate.

Pilot flow limitation

With pilot-operated directional valves, the throttle check valve can be applied for switching time adjustment (pilot flow limitation). In this case, it is installed between the pilot control valve and the main valve.
