[Equest-users] Secondary Loop Valve Type

[Darryl Kasun via Equest-users]

Hi eQUESTers,

For a secondary loop, there is an input for valve type - either three way
or two way.  Can anyone provide a schematic or quick explanation of the
difference between how these two valves control the flow from the primary?
Is this input assuming there is a valve at the secondary loop connection?
If there is a simply a tee at the secondary connection, can the valve head
input be zero?
