Product Overview
The SANY MBFB-4120 / DPA1177-SS1N-0E1S is a high-performance solenoid-operated directional control valve engineered for precise hydraulic circuit switching in demanding industrial and mobile machinery applications. Manufactured to SANY’s stringent quality standards and cross-referenced under the DPA1177-SS1N-0E1S designation, this valve utilizes a robust spool-and-sleeve architecture actuated by a wet-armature solenoid, enabling reliable directional control of hydraulic flow with fast response and minimal internal leakage. As a standard directional control valve, it serves as a critical control element in hydraulic systems, directing pressurized fluid to actuators, cylinders, and motors to manage extension, retraction, and holding functions with repeatable precision.
