Hot/chilled water or 50% water-glycol solutions in closed
loop systems enter the valve and pass through a variable
rectangular adjustable flow limiter (C) that is connected to
the ring with the dial (A) for presetting the maximum
volumetric flow.
The medium then flows through the temperature control valve
(D) with a linear characteristic and a stroke of 5 or 6.5 mm.
A powerful spring (B) ensures safe closing.
Before leaving the valve, the medium passes through a second
throttling point (E) controlled by the built-in mechanical
automatic differential pressure regulator (F).
This regulator is the heart of the valve and ensures that the selected
volumetric flow is maintained across the whole differential pressure
working range.
