Abstract
A valve with a valve housing for controlling the liquid flow in a plant for central heating is provided. The valve includes 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 includes a closure part which is disposed such that, upon axial displacement, the closure part is capable of completely or partially closing off the total opening area through the through-flow openings.
