<p>The valve has a valve body (1) with a mechanical connection for actuating a stopper, which allows/prevents flow of fluid in fluid ducts. An electromagnetic actuator (3) is arranged to actuate the connection, and includes a casing (6) placed around a winding (5), where the casing is made of plastic. The casing holds a ferromagnetic washer against an end of the winding to form a pole of a magnetic circuit. A coupling is provided between the actuator and the valve body, and is engaged with a shoulder (50). The shoulder has an assembly of two matching half-washers engaged in a groove.</p> |
