Seat Valve electrically force-controlled
Series 27-05
Valve B2704/0501/4278-AB DC
Solenoid valve for gases and solid-free liquids. The seal at the valve seat is made by a rubber diaphragm. Force-operated solenoid valves can be used where direct-acting valves are required. The valves operate from 0 bar pressure difference and combine the advantages of servo- and direct-acting valves. An unusually large variety of options make the 27 series with flange connection the specialist 'par excellence'.
