The series datasheet lists this coil for N2W and N2S valves in body sizes 160, 200 and 250. Verify the complete valve part number and the coil dimensions before ordering.

No. This is an electrical replacement coil and DIN connector. The brass or stainless valve body, diaphragm and fluid connections are not included.

Yes. The matching DIN Form A connector is included with this replacement coil.

No. Select the coil that matches the actual control-circuit supply. This part requires 24VDC; AC and DC coils are not interchangeable merely because they fit a similar valve body.

Only if the leak is caused by failed electrical actuation and the valve internals are otherwise sound. A damaged diaphragm, contaminated seat or incorrect seal material requires separate mechanical inspection and repair.

Replacement is possible on correctly identified equipment, but qualified personnel should isolate electrical power and process pressure and meet the applicable wiring and plumbing requirements.

The coil generates the magnetic force used to operate the valve. The diaphragm and seals are wetted mechanical parts that establish the flow path and shutoff. They correct different failure modes.
