The present inventive concept relates to a valve arrangement comprising: a valve inlet,a valve outlet arranged downstream of the valve inlet,a first chamber arranged directly downstream of theinlet, and a second chamber arranged between the first chamber and the valve outlet. The valve arrangement further comprises a measuring nipple comprising a measuring channel for receiving a measuring device, and a closing arrangement having open positions and a closed position, wherein the closing arrangement in its closed position is configured to prevent fluid communication between the first chamber and the second chamber via the closing arrangement, and wherein the closing arrangement in its open positions is configured to allow for fluid communication between the first chamber and the second chamber via the closing arrangement. A first passage is arranged between the first chamber and the measuring channel without passing the second chamber, the first passage enabling measuring of fluid pressure in the first chamber. A second passage is arranged between the second chamber and the measuring channel without passing the first chamber, the second passage enabling measuring of fluid pressure in the second chamber. The measuring nipple comprises the first passage and the second passage. |
