<p>PCT No. PCT/EP95/02774 Sec. 371 Date May 14, 1996 Sec. 102(e) Date May 14, 1996 PCT Filed Jul. 14, 1995 PCT Pub. No. WO96/02782 PCT Pub. Date Feb. 1, 1996A modular valve for fluids comprises a valve housing (16) having a plurality of fluid ports, a spring-loaded switching rocker (18) which is adapted to be inserted into the valve housing (16), and an electromagnetic valve drive (20). Between the valve housing (16) and the electromagnetic valve drive (20) a generally magnetically non-conductive plate (30) is inserted having locally limited magnetically conductive regions (32, 34) for the electromagnetic valve drive (20) to act through on one of two limbs of the switching rocker (18), whereas the other limb is not able to be acted upon magnetically. Valve members provided at the opposite ends of the switching rocker (18) and poles (44, 46, 48) of the electromagnetic valve drive (20) are arranged symmetrically with respect to a plane containing the rocker axis (50) and perpendicular to the intermediate plate (30). The valve housing (16), the switching rocker (18) with an associated spring loading means (66), the intermediate plate (30) and the electromagnetic valve drive (20), able to be coupled with an electrical connection part (60), are able to be alternatively mounted in two positions angularly spaced by 180 DEG about an imaginary axis (96) perpendicular to the rocker axis (50) and in the plane of symmetry.
