The Bosch Rexroth Z2FS10-3-3X/VSO30 (R901082914) is a high-performance industrial hydraulic valve designed for reliable throttling of flow to a set value. This mechanically actuated valve features a lockable rotary knob with scale, enabling precise adjustments to the flow rate. The model is equipped with spool symbols A A, B B or A A, B B, indicating its capability to control the flow in specified directions.
This valve falls under the product group ID ZFS and is recognized for its role in both main and pilot flow limitation for one or two actuator ports. It employs two throttle check valves arranged symmetrically to manage flows in one direction while allowing free return flow in the opposite direction. The design ensures that when supply throttling occurs, hydraulic fluid is directed efficiently through the appropriate channels and throttling points.
The Z2FS10-3-3X/VSO30 can be adjusted via a spindle for optimal control of the throttling point, maintaining the throttle spool in position using pressure and spring force. It also functions as a check valve during return flows from actuators, displacing the throttle spool against a spring to permit unobstructed flow.
For applications requiring actuator velocity adjustment through main flow limitation, this valve is installed between the directional valve and subplate. In scenarios involving pilot-operated directional valves for switching time adjustment via pilot flow limitation, it's placed between the pilot control valve and main valve.
This sandwich plate valve adheres to ISO porting patterns and offers various adjustment types including meter-in or meter-out throttling. It boasts corrosion protection and has specifications that include size CETOP D component series X with a maximum operating pressure of bar and maximum flow rate of l/min. Its design includes FKM seals compatible with various hydraulic fluids like HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, HFDR ensuring versatility across different hydraulic systems.

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.
