Abstract
A fluid regulator includes a valve block having an inlet arranged for connection to a gas supply and an outlet arranged for connection to an item of gas equipment and defining a flow path. The valve block may include one or more of a pressure regulator, a metering valve, and an on-off switch disposed in the flow path. A rotatable pinion operatively is coupled to the metering valve, and a hand control is coupled to the valve block and rotatable about an axis and includes a toothed rack movable with the hand control. A spring biases the toothed rack toward pinion to provide improved precision and/or less play between internal components. The fluid regulator they also include a balanced gear assembly for rotating a control rod of the valve, and further may be adapted to provide various visual indicators of the on-off the state of the device.
