The Duplomatic MD1D-S3/50 is a high-performance, direct-operated solenoid directional control valve designed for reliable operation in hydraulic systems. It conforms to the ISO 4401-03 (CETOP 03) mounting standard, ensuring interchangeability and ease of installation. This valve features a wet armature solenoid with a manual override pin for emergency actuation. The valve body is constructed from high-strength cast iron, providing durability and stability even under high pressure. The S3 spool configuration is a 3-position, spring-centered type, which blocks the A and B work ports and connects the pressure port (P) to the tank port (T) in its neutral position. It is ideal for applications requiring precise control over the start, stop, and direction of fluid flow.
