A programmable drive and control assembly (2) for a solenoid valve, in particular for irrigation systems is described. The assembly (2) comprises a drive solenoid (7) for a hydraulic valve (1), a programmable electronic control device (10) for said solenoid (7), and a containment box (8, 23) for said solenoid (7) and said programmable electronic control device (10). The containment box (8, 23) comprises a box-like body (8) removably fixable to said hydraulic valve (1) and an at least partially transparent closing cover (23) screwed at the upper end of said box-like body (8) with the interposition of a fluid-tight annular gasket (25). The programmable electronic control device (10) is press-fitted into the upper end of said box-like body (8) below said cover (23) and comprises a resin body (11) for fluid-tightly accommodating an electronic circuitry (12) and at least one electric battery, a display (16) overlapping said electronic circuitry (12) and a transparent body (19), having a keyboard (20) overprinted by injection, overlapping said resin body and said display (16) The fluid-tight annular gasket (25) is accommodated in an annular conduit (26) of the upper end of the box-like body (8) so as to achieve a sealed side coupling with the closing cover (23). The box-like body (8) is fixable to the body (3) of the hydraulic valve (1) by means of screws (9).
