Description
Valve 0290 is a servo-controlled diaphragm valve of the S.EV series. The valve opens without differential pressure. The opening process is supported by the fixed coupling of the diaphragm to the anchor. The integrated soft kick function ensures gentle opening of the material. Different diaphragm materials are available according to the applications. The housing offered is rounded off by stainless steel variants. The coils are crimped with a chemically high-resistance epoxy. For reducing the electrical power consumption a "kick and drop" electronics are cast in the coil for all DC versions. NEMA 4X is available on request.

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
