A VALVE

摘要

The invention relates to a valve with a valve housing in particular for controlling the liquid flow in a plant for central heating. The valve comprises an insert part with valve parts for controlling a liquid flow through the valve: a first part and a second part being mutually rotatable. The first and the second parts are provided with complementary through flow openings that combine to define a common opening area and are configured such that upon mutual rotation of those valve parts a larger or a smaller total opening area is provided. The valve comprises a closure part which is disposed such that upon axial displacement it is capable of completely or partially closing off the total opening area through the through flow openings.
