Each 1179 unit has two serial number labels, a small one on top side and the standard, larger
label on the back side. Each label shows the serial number, the model code, the full scale flow

Control Valve (MFC only)
The Control Valve is a specially constructed solenoid valve in which the armature (moving valve
mechanism) is suspended by two springs. This arrangement ensures that no friction is present
and makes precise control possible. The 1179 controller has the valve normally closed, the
control current is used to lift the armature from the seat, allowing a controlled flow of gas.
