OPERATION :
Valve Type 6616E - In normal
condition, ‘A’ port is closed and
‘AB’ port is connected to ‘B’ or
‘B’ port is connected to ‘AB’ port.
on receiving pilot pressure, ‘A’
port is connected to ‘AB’ or ‘AB’
port is connected to ‘A’ closing
port B.
Valve Type 6619E - Normally
‘B’ port is closed and ‘A’ port is
connected to ‘AB’ or ‘AB’ port is
connected to ‘A’. On receiving
signal ‘A’ port is closed and ‘B’
port is connected to ‘AB’ or ‘AB’
port connected to ‘B’. |
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. |
