The valve is also frequently used as a pilot valve for pneumatic valves. A rocker with sealing seats alternately closes valve seats 1 for the air supply (fluid port P) and 2 for venting (fluid port R) of the outlet channel (fluid port A) (see Figure), in a similar manner to the pivoted- armature valve. Solenoid valves with rocker technology are available
with or without isolating diaphragm.
