Bosch Rexroth LC32DR20E7X/ normally-open pressure-reducing logic insert

LC32DR20E7X/, manufacturer material number R900912562, is a Bosch Rexroth size 32 normally-open pressure-reducing logic insert. It is an individual insert for an ISO 7368 receiving cavity and requires a separately selected control cover. It is normally open from B to A and closes as the downstream pressure at A reaches the pilot-controlled level.

The construction is a spool without fine control grooves. Spring code 20 identifies an approximate 2 bar closing pressure class; it does not specify the assembled system pressure setting. The seal code specifies NBR.

The original reference gives a 315 bar insert limit at A and B and a recommended 300 L/min flow limit for this size and construction. These are component data, not a complete-valve rating. The selected cover, pilot, manifold and operating conditions determine the permissible assembly limits. Pressure-flow curves use HLP46 oil at 40 ± 5 °C; drain backpressure and pilot configuration affect the result.

Technical reference: manufacturer-authored RE21050 compiled edition 2003-02, containing retained earlier page revisions. The dated reference identifies applicable component design data and does not establish current stock or an individual assembly setting.
