  • Flow control valve with a flow meter
    Patent number: 5890515
    Abstract: The height of the valve with a flow meter shall be as small as possible, enabling it to be mounted in restricted spaces. In order to achieve this, all adjusting and display movements are not executed axial but on the contrary polar. The rotating spindle of the valve is designed as rotary slide valve and the display marker or the graduation of the display unit of the flow rate meter is present on a rotating bush. The total height of the valve with a flow meter is accordingly low and unchangeable.
