The present invention relates to a valve (10) comprising a housing (11) having a peripheral structure (12) made of a magnetic field conductive material and a core (13) disposed in said housing (11) The core (13) and the peripheral structure (12) delimit a first chamber (14) disposed on one side of the core (13), a second chamber (15) disposed on another side of the core (13). The valve (10) further comprises at least one channel (16) formed between the peripheral structure (12) and said core (13), this channel (16) connecting said first chamber (14) to said second chamber (15). The housing (11) contains a magnetorheological fluid (MRF). The valve is characterized in that the core (13) comprises an electropermanent magnet (EPM). The invention further concerns a control system comprising a valve as defined above, said control system comprising a control module arranged to transmit to said coil (17), an electric pulse having a direction chosen so as to open or close said valve (10). The invention also relates to a method of controlling a valve as defined above. Said method comprises the steps of choosing whether the valve (10) is to be open or closed; applying an electric pulse to the coil (17) surrounding the core (13) of the EPM so that the core allows the passage of the MRF through the channel (16), from one of said first or second chamber (14, 15) to the other chamber in the event that the valve is to be opened; and applying an electrical pulse to the coil (17) surrounding the core (13) of the EPM such that the core (13) prevents passage of the MRF through the channel (16), from one of said first or second chambers (14, 15) to the other chamber when the valve needs to be closed.
