Bürkert Servo-assisted 2/2 way piston valve type 6407, article number 20015466. Order code: 6407-A20,0EGMSGM85-L-230/50-12.
The 6407 valve is a servo-controlled piston valve. The fixed coupling of the pilot valve and piston allows the valve to be opened without differential pressure. As a piston valve, the Type 6407 is particularly suitable for gas and steam, as well as liquids with a low operating temperature below 0 °C. To increase pressure and leakage protection, the plug and core guide tube are welded together. Depending on the application, different sealing material combinations are available. The coils are pressed with chemically highly resistant epoxy. To reduce electrical power consumption during operation, coils with integrated kick and drop electronics are available in double coil technology. In conjunction with a plug in accordance with DIN EN 175301-803 Form A, the valves meet protection class IP65.
