Ball valve, 3/4" NPT, with sensor sleeve

This ball valve has a M10 x 1 fitting opposite the lever for insertion of the temperature sensor 01/BFPT1000 5x60MM for a heat meter arrangement. The ball also has a hole at that location. This places the sensor in the flow channel at the centre of the ball. When the valve is shut off, the sensor is sealed off as well, allowing it to be removed easily (e.g. for calibration).
