The LFA 32 E-71/CA20DQMG24F control cover is part of the LFA 2 Way Control Covers series produced by Bosch Rexroth for hydraulic automation tasks that require dependable flow regulation and pilot control. It fits a size 32 cavity manufactured to ISO 7368, so it mates directly with standard two-way cartridges in manifold blocks. An area ratio of 2:1 balances hydraulic forces across the poppet to keep actuation effort low. The poppet uses a damping nose that moderates pressure transients and protects downstream components. A cracking pressure of 2.0 bar defines the point at which initial flow begins, while a monitored maximum operating pressure of 400 bar sets the allowable system limit. Port X is tapped M6, providing a dedicated pilot line for remote operation. NBR sealing elements are fitted to maintain fluid containment with common mineral-oil media.
Closed-position monitoring is integrated so machine controls can verify that the valve element has seated before issuing further commands. The position switch is an inductive QM type that senses metallic movement without mechanical contact. It is powered from a 24 V DC supply, draws 40 mA during operation, and delivers a PNP output able to source up to 400 mA for direct connection to PLC inputs or relays. An M12 × 1 four-pin connector simplifies field wiring and supports quick replacement. The complete cover weighs 4.0 kg, allowing manual installation onto manifolds without lifting equipment.
