Product Description
Rexroth LC25DB20E7X Logic Cartridge Check Valve
The Rexroth LC25DB20E7X is a high-performance logic check valve insert designed for cavity mounting according to ISO 7368. As part of the LC..DB..E series, this cartridge valve provides reliable free flow in one direction while ensuring leak-free blocking in the opposite direction using a poppet design. It is intended for integration into hydraulic control blocks and manifolds, offering a compact and efficient solution for directional control tasks in various industrial hydraulic systems. The ’20’ designation indicates a 2.0 bar cracking pressure, and the ‘E’ signifies NBR seals suitable for standard mineral oil-based hydraulic fluids.
