MDS3 switching solenoid valve is a modular valve for the switching of multiple courses or for the selection of pressure values. The fluid ducts cross the entire valve body and thanks to this particular design, the MDS3 valve can be stackable with all the other modular valves with ISO 4401-03 laying plan. The special connection of the valve in parallel to the P-A-B lines of the circuit allows multiple hydraulic figures, minimizing load losses. The valve is available for continuous or alternating current power supply. The continuous current valves can also be powered as an alternation, upon use of connectors with built -in strainer bridge. As an alternative to the standard emergency manual command, the emergency control command are available, with bellows and different mechanical arrest devices.
