Burkert Type 6407 Servo-assisted 2/2-way Piston Valve

The Burkert Type 6407  piston valve is a servo-assisted piston valve. The fix coupling between pilot valve and piston provides an opening of the valve without pressure difference. As a piston valve, the Type 6407 is particular 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 moulded 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 IP65 degree of protection. This product can be combined with Cable Plug DIN EN 175301-803 – Form A Type 2518 and Timer Type 1087
