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.

Fluid regulator

In a drying balance with a balance pan (,) which rests removably on the load receiver (,) of a weighing system, a radiation source (,) for warming and drying a substance on the balance pan (,), and a temperature calibrating disk (,) with at least one built-in temperature sensor (,), the load receiver (,) has a vertical hole (,) into which a pin (,) on the underside of the balance pan (,) protrudes. The housing (,) of the balance has an opening (,) around the hole (,) in the load receiver (,) which is significantly larger than the diameter of the pin (,). The temperature calibrating disk (,) has a plug (,) on its underside with several contacts (,) on the outer edge, which protrudes into the opening (,) without contacting the load receiver (,). The plug (,) establishes an electrical connection with the corresponding mating contacts (,) at the opening (,). The plug (,) has three contacts (,) which are held in a synthetic material part. Thus, the temperature calibrating disk (,) is electrically and mechanically easily connectable with the housing (,) such that it does not contact the load receiver (,).
