原裝burkert 6281EV A/B電磁閥The 6281 valve is a servo-assisted solenoid valve of the S.EV series. A minimum differential pressure is always required for the proper function of the valve.原裝burkert 6281EV A/B電磁閥 Various diaphragm material combinations and methods of operation are available depending on the application. The standard brass housing satisfi es all European drinking water requirements. Dezincifi cationresistant brass is available for other markets. The housing offering is rounded out by a stainless steel version. The solenoid coils are moulded with a chemically resistant epoxy. For reduced energy requirement, all coils can be delivered with electronic power reduction. The valve can be equipped with manual override for easy maintenance and commissioning.
