Product Overview
The Danfoss MD1D‑TA/59N‑A/DMS is a heavy‑duty marine‑spec solenoid directional control valve built for offshore and shipboard hydraulic installations. It switches hydraulic flow paths via electrical solenoid actuation, controlling the direction of hydraulic actuators. Built to withstand high vibration, humidity and harsh marine environmental conditions, this valve is widely used as critical spare component for retrofitting existing vessel hydraulic systems.
Series
MD1D series DMS marine directional solenoid valves include multiple coil variants: MD1D‑TA, MD1D‑RK, MD1D‑SA with DMS marine qualification. These units are manifold‑mount hydraulic valves designed specifically for ship and offshore hydraulic circuit control.
Product Features
- Marine‑grade construction resistant to shock, vibration and high‑humidity offshore environment
- High maximum working pressure rating for heavy‑duty hydraulic service
- Manifold mounting form factor, compact footprint for cabinet and hydraulic power unit installation
- Solenoid coil electrical actuation for remote directional control
- Robust internal spool design for reliable hydraulic flow switching
- Qualified for marine system requirements, widely adopted on commercial vessels and offshore platforms
- Interchangeable spare coils for field maintenance and repair
