A range of helpful accessories makes it easier for the system integrator to plan and build systems for gas analysis. An important component used between the sampling point and the analysis system are heated lines to prevent cold spots. These are available for both safe and explosive areas with a wide range of options making them suitable for virtually any application. The back pressure regulators are used in analysis systems downstream of the oxygen analyser in order to eliminate the impact of the air pressure variation on the outlet, thus preventing deviations in the measurements.
For adjusting the flow rate, needle valves of the NVT-3 series are particularly suitable for corrosive gases. The valve body and the needle itself are made from solid PTFE for maximum durability. Adding test gas or similar functions can easily be integrated in analysis systems with multi-path ball valves from the GKH series. We offer various styles and materials. Plastic or stainless steel fittings and connectors for hose and glass junctions are the ideal addition to these products. Plastic fittings are available in a variety of materials such as PVDF, PFA, ensuring they are suitable for special corrosion resistance. We offer a wide range of thread sizes and shapes to suit any application.
To manage various pressure ranges, flow rates, and material resistance requirements, pressure regulators by GO offer a variety of solutions.
