Abstract: An electrovalve (1) comprising a valve body (2), said valve body (2) delimiting at least one inlet opening (4), and at least one outlet opening (6); and wherein said electrovalve (1) further comprises a plunger element (11) movable between at least one closing position and at least one opening position; and wherein said electrovalve (1) comprises a moving assembly (12) adapted to move said plunger element (11) between said at least one opening position and said at least one closing position; and wherein said plunger element (11) comprises at least one sealing surface (13) which forms an abutment reference adapted to cooperate with a counter-sealing surface (33) provided in the walls of said plunger housing (48) and which delimits at least one portion of the plunger housing (48) forming a seal for a process fluid associable with the electrovalve (1), when said plunger element (11) is in said at least one closing position; and wherein said electrovalve (1) comprises an inlet chamber sealing element (15) associated with said plunger element (11) and associated with said inlet chamber walls, wherein said inlet chamber sealing element (15) by permitting the movement of said plunger element (11), forms at least one wall of said inlet chamber (8), and an outlet chamber sealing element (16) associated with said plunger element (11) and associated with said outlet chamber walls, wherein said outlet chamber sealing element (16) by permitting the movement of said plunger element (11), forms at least one wall of said outlet chamber (10); and wherein said outlet chamber sealing element (16), defines a thrust area (S3), or third thrust area (S3), on which the process fluid acts; and wherein said thrust areas (SI, S2, S3) are substantially mutually equal, so that said plunger element (11) is in hydrostatic balance both when it is in said at least one opening position and when it is in said at least one closing position.
