The 6213 EV valve is a servo-controlled diaphragm valve from the S.EV series. The spring coupling of the membrane supports the opening process of the valve. In the standard design, the valve is suitable for use in liquids. A minimum difference pressure is required to fully open. For gas and vacuum applications, a separate version (HP00) is available, which opens the valve without differential pressure. According to the applications, different membrane materials are available. The standard brass housing meets all European drinking water requirements. Zinc resistant brass is available for other markets. The case is rounded off by a stainless steel version. To reduce electrical power consumption during operation, coils with integrated "Kick and Drop" (KD) electronics are available in dual coil technology. In combination with a plug according to DIN EN 175301-803 Form A, the valves meet the protection class IP65 - in combination with a stainless steel housing NEMA 4X.
