Mixing loop, double shunt with 3-way valve, type 1
A double shunt mixing loop is characterised with constant flow on the primary side which is causing high pumping energy costs. A double shunt mixing loop is normally fitted with a 3-way valve.
Mixing loop, single shunt with 3-way valve in return pipe
A single shunt mixing loop with 3-way valve in return is used when variable flow is desired on the secondary side and variable temperature is undesirable.
