Description
The valve 6281 is a servo-controlled diaphragm valve of the S.EV series. A minimum differential pressure is always required to operate the valve. Depending on the applications, different membrane materials and modes of action are available. The standard measuring housing meets all European drinking water requirements. For other markets, uncut brass is available. The housing range is rounded off by a stainless steel version. All coils can be supplied with an electronic power reduction to reduce energy requirements. The valve can be supplied with a manual actuation for easy maintenance and commissioning. In conjunction with a plug in accordance with DIN EN 175301-803 Form A, the valves fulfill the IP65 degree of protection – in conjunction with a NEMA 4X stainless steel housing.
