Description
Valve 0331 is a direct-acting, media-separated hinged valve. It is available in 3/2- and 2/2-way versions. As 3/2-way version it can be used as distributor or mixing valve. Depending on the applications, different membrane materials and modes of operation are available. The housing range comprises brass, stainless steel, PEEK and polypropylene. The coils are crimped with a chemically high-resistance 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. The 0331 is equipped with manual operation for commissioning and testing. To reduce the power requirement, all coils can be supplied with an electronic power reduction or as a pulse version. The switching state can be sent via a position feedback signal as binary or NAMUR signal.
