多端口气体采样阀

The Multi-Port Ambient Air Sampling Valve is a selector valve that works in conjunction with an analyzer to monitor ambient air quality at multiple locations. This unique ambient stream selection system provides a method to select one of thirty-two air sample lines for delivery to an analyzer while maintaining full flow through the remaining thirty-one unselected lines. This provides a representative sample at all times. The absence of multiple automatic valves allows for reduced maintenance time and cost.
