Caleffi Differential Bypass Valves
The differential by-pass valve is used in systems working with
variable flow rates, for example in those making widespread use of
thermostatic valves or 2-way motorised valves. It ensures a flow
recirculation proportional to the number of valves being closed,
while limiting the maximum differential pressure value generated by
the pump. Available in two standard sizes for hot water systems
1060 kPa (16 m w.g.).
(In chilled water systems with high head pumps, installation of the
version with a setting range between 100 and 400 kPa is advisable.
