Bosch Rexroth WL70-4-A Coil

Bosch Rexroth WL70-4-A Coil is a solenoid coil replacement for the WL70 family of hydraulic directional valves. It operates at 120 V and is used to energize the valve solenoid to shift the spool, enabling precise control of hydraulic flow within Rexroth valve assemblies. This WL70-4-A coil is designed to fit WL70-4-A valve bodies and Rexroth WL70 installations, providing a direct replacement in compatible systems. Typical applications include industrial automation equipment, machine tools, presses, and automated production lines where Rexroth WL70 valves regulate hydraulic actuation. When installing, verify that the coil matches the WL70-4-A part number to ensure proper fit and electrical interface with the existing Rexroth valve block. As part of Bosch Rexroth’s hydraulic control portfolio, the WL70-4-A coil converts electrical energy into magnetic actuation to move the spool and control hydraulic circuits in demanding industrial environments.
