The Bosch Rexroth Z2FS10A5-3X/S (R900989099) is a high-performance industrial hydraulic valve designed for reliable flow throttling to a preset value. This mechanically actuated valve features a spool symbol A A or A A and is capable of handling maximum pressures with ease. The Z2FS10A5-3X/S is part of the product group ID and comes with a specified number of ports for versatile applications. The valve is notable for its direct actuation and the spindle equipped with an internal hexagon and scale, allowing precise adjustments. It can be used in various configurations, including meter-in or meter-out throttling, and offers an adjustable throttle spool for fine-tuning flow rates. Additionally, it boasts a corrosion-protected design, ensuring longevity even in harsh environments. This sandwich plate valve adheres to the porting pattern according to ISO standards and can be utilized for both main or pilot flow limitation across one or two actuator ports. Various adjustment types are available, including a lockable rotary knob with scale, further enhancing its versatility. The size component series X indicates that it can withstand a maximum operating pressure of bar while allowing a maximum flow rate of l/min. The Bosch Rexroth Z2FS10A5-3X/S valve's robust construction includes NBR seals compatible with hydraulic fluids such as HL, HLP, HLPD, HVLP, HVLPD, and HFC. With its diverse capabilities and reliable performance, this valve is an essential component in sophisticated hydraulic systems requiring precise control over fluid dynamics.

THROTTLE CHECK VALVE Z2FS10A5-3X/S

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: 2.980 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.
