METERING VALVE FOR GAS SAMPLES
The metering valve for the introduction of gas samples is designed for the introduction of gas under excessive pressure into the chromatograph. Cranes differ in the number of moves (4, 6, 8, 10, 12) and have two provisions "Selection" — "Analysis". In addition to dosing, cranes can be used to switch chromatographic columns, elements of gas circuits, etc. The tap can be installed either on the side panel of the chromatograph, or directly into the analytical module instead of, or together with the evaporator of the chromatograph, while it is used as a back-purge tap or for hot sample entry. Additionally, the tap for hot entry can be equipped with heated pipelines.
technical specifications
The dose volume is from 0.25 to 5.0 ml (at the request of the consumer, the dose volume can be increased to 10 ml and reduced to 0.1 ml).
The maximum temperature of the tap is no more than 160 °C.
The pressure in the crane line is not more than 0.48 MPa.
The angle of rotation of the crane handle — depending on the number of strokes.
