The Burkert Type 6407 piston valve is servo-assisted. The fixed coupling between the pilot valve and piston provides an opening of the valve without pressure difference. As a piston valve, the Type 6407 is particularly suitable for media such as gas and steam. As well as liquids with low operating temperature below 0°C.
The stopper and the core guide pipe are welded together to enhance pressure resistance and leak-tightness. Various seal material combinations are available depending on the application. The coils are molded with chemically resistant epoxy.
To reduce power consumption in operation coils with “Kick and Drop” (KD) electronics (double coil technology) are available. In combination with a plug acc. to DIN EN 175301-803 Form A, the valves satisfy the IP65 degree of protection. This product can be combined with Cable Plug DIN EN 175301-803 – Form A Type 2518 and Timer Type 1087
