Seat Valve electrically force-controlled
Series D24-04
Valve D2408/0404/4278-7P DC
2/2-way solenoid valve made of high-quality grey cast iron EN-GJL250, internal parts made of stainless steel and brass. The sealing element is a metal piston with an annular seat seal made of an elastomer or plastic. Force-operated valves combine the advantages of servo- and direct-operated valves. The valves do not require a pressure differential to open and are ideal for large nominal sizes. An unusually large variety of options make this category the specialist 'par excellence'.
