The valve 6430 is a servo-controlled 3/2-way piston valve. If the valve is not supplied with auxiliary control air, a minimum differential pressure is required for the function. Variants: - For neutral liquids and gases in the pressure range 1-16 bar in the NC and NO functions. - For technical vacuum up to 3 bar in the NC and NO functions. - With auxiliary control air for vacuum up to 8 bar in the NC and NO functions. All variants are available as pulse variants to ensure the respective switching state even in the event of a voltage interruption. For commissioning or manual function, the 6430 is equipped with manual operation (exception: pulse variant). To reduce electrical power consumption during operation, coils with integrated "Kick and Drop" (KD) electronics in double coil technology are available. A maintenance-free, media-separated 3/2-way folding armature valve type 0331 is used as the pilot valve. In conjunction with a plug in accordance with DIN EN 175301–803 Form A, the valves meet protection class IP65.
