Bosch Rexroth LC32A20D7X/ is a size 32 two-way logic cartridge insert, factory article R900912589, for an ISO 7368 manifold cavity. This individual insert requires a suitable control cover and pilot circuit selected separately. Its nominal seat-to-annulus area ratio is 2:1; pilot pressure and the closing spring act against pressure forces at ports A and B.
The A20 spring is the approximately 2 bar cracking-pressure class, not a required pilot pressure or a system pressure setting. The poppet has a damping nose. The standard execution uses NBR seals. Required opening pressure depends on the operating pressure and force balance.
Engineering dimensions and reference areas use the manufacturer’s March 2005 series document. The complete circuit pressure limit depends on the manifold, cover and attached pilot valve; no assembled-system rating or supplied setting is inferred. The manufacturer photograph is representative of an LC25 insert and does not identify every spring or poppet execution.
