Description
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 operation are available. The standard brass housing meets all European drinking water requirements. For further markets, zinc-resistant brass is available. The housing offered is rounded off by a stainless steel variant. In order to reduce the electrical power consumption during operation coils with integrated "kick and drop" (KD) electronics are available in double coil technology. The valve can be supplied with manual operation for easy maintenance and commissioning.

Hints
The kv factor indicates the volume flow through a valve, measured in litres/min at 1 bar and at a water temperature between 5 and 30°C. The QNn factor indicates the gas volume flow, measured in litres/min
