The Rexroth A4VG56/71/90/125 EP Hydraulic Proportional Solenoid Control Valve is a highly efficient electric proportional (EP) control assembly designed specifically for Rexroth A4VG series axial piston variable pumps. Compatible with pump sizes 56, 71, 90, and 125, this advanced control valve utilizes dual proportional solenoid actuators to precisely adjust the pump’s displacement and swivel angle in direct response to the electrical control current signal. Engineered for heavy-duty mobile and industrial hydraulic applications, the unit features a durable pilot control valve body, a precision-ported mounting face, and secure electrical connector terminals with protective caps. For added safety and operational flexibility, it is equipped with black knurled manual override caps on both ends, ensuring reliable performance even in the most demanding environments.
