Burkert 49969 (Type 0330) is a direct-acting, media-separated 2/2-way pivoted armature solenoid valve. 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 alkalis. The 49969 variant features a Polypropylene (PP) body and EPDM seals, making it highly resistant to alkaline washing and bleaching lyes.
