[ We claim:] [1.] A modular valve comprising a valve housing with a plurality of fluid ports and a switching rocker, said switching rocker having two limbs with opposite ends and a pivot axis, said switching rocker further being arranged and pivotally mounted within said valve housing, a closure member being provided at each of said opposite ends of the switching rocker, the valve further comprising spring means which urge said switching rocker into an initial position and an electromagnetic valve drive adapted to be fitted to said valve housing in a position opposite to said switching rocker, said valve drive having magnetic poles for attracting and moving said switching rocker into an operative position against the force of said spring means, a valve seat where one of said fluid ports opens and against which said closure member may be applied, a generally magnetic non-conductive intermediate plate being arranged between said valve housing and said electromagnetic valve drive and having locally limited magnetically conductive regions through which said electromagnetic valve drive acts on one of said limbs while the other of said limbs is not able to be acted upon magnetically,said closure members and said magnetic poles being symmetrically arranged with respect to a plane of symmetry perpendicular to said intermediate plate and containing said pivot axis in the assembly state of the valve; andsaid valve housing, said switching rocker with said spring means and said intermediate plate being mounted alternatively in two orientations angularly spaced from each other by 180.degree. about an imaginary axis which is perpendicular to said pivot axis and contained in said plane of symmetry.
