The valve 6213 EV is a servo-controlled diaphragm valve from the S.EV series. The spring coupling of the diaphragm assists in the valve's opening process. In its standard version, the valve is suitable for use in liquids. A minimum differential pressure is required for full opening. For gas and vacuum applications, a special version is available that opens the valve without differential pressure. Depending on the applications, different diaphragm materials are available. The standard brass housing meets all European drinking water requirements. For other markets, dezincification-resistant brass is available. The housing range is completed by a stainless steel variant. To reduce electrical power consumption during operation, coils with integrated "Kick and Drop" electronics in double coil technology are available. In conjunction with a connector according to DIN EN 175301-803 Form A, the valves meet the protection class IP65 – in combination with a stainless steel housing NEMA 4X.
