## Abstract

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.

## Claims

### Claim 1

A valve with a valve housing, in particular for controlling the liquid flow in a plant for central heating, said valve comprising:
an insert part with a first part and a second part for controlling a liquid flow through the valve, said first part and said second part being mutually rotatable and provided with complementary through flow openings that combine to define a common opening area, said through-flow openings being configured such that, upon mutual rotation between the first and the second part, a larger or a smaller total opening area is provided, and a separate closure part which is disposed such that, upon axial displacement, said separate closure part is capable of completely or partially dosing off the total opening area through the through-flow openings.

### Claim 2 (depends on 1)

The valve according to claim 1 further comprising a membrane guide.

### Claim 3 (depends on 1)

The valve according to claim 1, wherein the first part is stationary relative to the valve housing.

### Claim 4 (depends on 1)

The valve according to claim 1, wherein the second part is stationary relative to the valve housing.

### Claim 5 (depends on 1)

The valve according to claim 1, wherein the second part is rotatably journalled within the first part.

### Claim 6 (depends on 1)

The valve according to claim 1, wherein the closure part has a cylindrical portion for insertion into the second part.

### Claim 7 (depends on 6)

The valve according to claim 6, wherein the closure part is rotatably journalled within the second part.

### Claim 8 (depends on 1)

The valve according to claim 1, wherein the closure part and the second part are configured such that relative to each other, the closure part can be shifted only axially relative to the second part.

### Claim 9 (depends on 1)

The valve according to claim 1, wherein the closure part comprises a plastic material.
