Valve 6430 is a 3/2-way piston valve. If the valve is not supplied with auxiliary air, a minimum differential pressure is required for the function. Versions: - for neutral liquids and gases in the pressure range 1-16 bar in the function NC and NO. - for technical vacuum up to 3 bar in function NC and NO. - with auxiliary control air for vacuum up to 8 bar in function NC and NO. All versions are available as pulse versions, in order to secure the respective switching state even in the event of a voltage interruption. For commissioning or manual operation, the 6430 is equipped with manual operation (except pulse version). Coils with integrated Kick and Drop (KD) electronics are available in double coil technology to reduce electrical power consumption during operation. A maintenance-free, media-separated 3/2-way folding tank valve type 0331 is used as the pilot valve. In conjunction with a plug according to DIN EN 175301 â 803 Form A, the valves fulfill the protection class IP65.This text is machine translated.
