Series 43 solenoid valves, suitable for gases and liquids without solids, seal the valve seat with the help of a rubber diaphragm. Force-controlled solenoid valves are ideal for applications where direct-acting valves are required. These valves work from as little as 0 bar pressure difference and combine the advantages of servo- and direct-controlled valves. An unusually wide range of options make the 43 series with threaded connections the specialist par excellence.
