| OPERATION : |
 |
Valve Type 7416B -Normally ‘A’ port is closed
and ‘B’ port is connected to ‘AB’ or ‘AB’ port is
connected to ‘B’.On receiving signal ‘B’ port is
closed and ‘A’ port is connected to ‘A’ or ‘AB’
port is connected to ‘A’.
Mixing :
Valves can be used for introducing two different
fluids (mixing) through two different ports to
common port ‘AB’.
Diverting :
One fluid coming through port ‘AB’ can be
diverted to ‘A’ port or ‘B’ port. |
