The 0331 valve is a direct-acting, media-separated pivoted armature valve. It is

available as a 2/2 and 3/2-way variant. As a 3/2-way variant, it can be used as a

distributor or mixing valve. Various diaphragm materials and circuit functions are

available depending on the actual application. Brass, stainless steel, PEEK and

polypropylene bodies are offered. The solenoid coils are moulded with a chemically

resistant epoxy. Since the coil system is separated from the medium by a diaphragm,

the valve is especially suitable for critical media such as aggressive acids

and lyes. The 0331 is equipped with manual override for start-up and testing. To

reduce energy demands, all the coils can be delivered with electronic power reduction

or as an impulse variant. The switching status can be indicated via position

feedback as a binary or NAMUR signal.
