The valve 6281 is a servo-controlled diaphragm valve from the S.EV series. A minimum differential pressure is always required for the valve to function. Depending on the applications, different diaphragm materials and modes of operation are available. The standard brass housing meets all European drinking water requirements. For other markets, dezincification-resistant brass is available. The housing range is complemented by a stainless steel variant. To reduce energy consumption, all coils can be supplied with electronic power reduction. The valve can be delivered with a manual actuator for easy maintenance and commissioning. 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.
