The arrangement for controlling the flow of laden gases is arranged upstream of an oil separation system and is provided with a check valve, a bypass valve and a stationary segment. The check valve is at least partially movable so as to define a first passage for a forward first flow direction in the event of positive pressure, while the bypass valve is moved rearward by negative pressure so as to clear a second passage for a second, opposite, flow direction. The stationary segment forms a seating surface for the bypass valve. The bypass valve, urged against the seating surface by an elastic biasing member, forms a seat for the check valve. In the event of sufficient negative pressure, the two valves are moved rearward together despite the biasing member and work together to redirect and guide the flow along an escape path corresponding to the second passage.

The present invention relates to a gas inlet system for an analytical apparatus. The gas inlet system comprises switchable flow restrictions for regulating gas flow rate. The invention also provides a system for calibrating gas flow rate in gas inlet systems, the system comprising a calibration line that comprises a gas flow meter, and that is arranged downstream of gas flow controllers in the gas inlet system. Methods of adjusting gas flow rates and methods of calibrating gas flow rates are also provided.

A flow control valve including a main valve and a pilot valve for controlling a piston of the main valve. The pilot valve is controlled in part with relatively high pressure fluid ported from a high pressure port of a flow sensor and relatively low pressure fluid ported from a low pressure port of a flow sensor, and also controlled with a control fluid applied to a control plate acting on a compression spring to bias the pilot valve. The pressure in the control fluid is controlled by pressurizing a control fluid reservoir with a mechanism accessible from outside the valve and the piping in which the valve is installed. The flow sensor and the reservoir are preferably disposed within the flange of the valve.
