The valve 0330 is a direct-acting, media-separated folding armature valve. It is available in 3/2 and 2/2-way variants. As a 3/2-way variant, it can be used as a distributor or mixing valve. Depending on the applications, different diaphragm materials and modes of action are available. The housing is made of brass, stainless steel, PEEK and polypropylene. The solenoid coils are pressed with a chemically highly resistant epoxy. Since the coil system is separated from the medium by a diaphragm, the valve is particularly suitable for critical media such as aggressive acids and alkalis. For commissioning and testing, the 0330 is equipped with manual operation. To reduce the energy requirement, all coils can be supplied with an electronic power reduction or as a pulse variant. The switching state can be carried out via position feedback as a binary or NAMUR signal.
