Bosch Rexroth Z2FS10B5-3X/S2V throttle check valve

Z2FS10B5-3X/S2V, factory material number R900517814, is a manually adjustable sandwich throttle check valve for working line B. It meters flow through an adjustable restriction and permits reverse flow through its check-valve path. This size 10 execution uses FKM seals and spindle with internal hexagon and scale. Its hydraulic arrangement is discharge throttling; use the specified B-line symbol and mounting diagram for installation.

Use the applicable manufacturer installation, fluid-compatibility and characteristic-curve conditions. Operating ceilings and pressure adjustment stages serve different purposes and must not be treated as a single simultaneous operating point.

The exact factory article lists a 315 bar operating-pressure ceiling while the linked 2025 series sheet states 350 bar. The article-listed 315 bar limit is retained; an increase requires manufacturer confirmation for this execution.
