burkert 6240 A/6活塞电磁阀The 6240 valve is a servo-assisted plunger valve. The stopper and plunger guiding tube are welded together to enhance pressure resistance and leak-tightness. Various seal material combinations are available depending on the application. The housing design and surface quality enable maximum fl ow rates.burkert 6240 A/6活塞电磁阀 The coils are moulded with chemically resistant epoxy. An optional sliding ring bearings increases the life cycle with dry gases. ‚Kick and Drop‘ electronics are available for over-excitation (plug 2511) and reduced electrical power consumption in operation. In combination with a plug in accordance with DIN EN 17301-803 Form A, the valves satisfy protection class IP65. Stainless steel valves satisfy NEMA 4X
