This valve is used for gas chromatography and other gas instruments to stabilize the inlet gas pressure, which can generate a stable pressure of the inlet gas in front of the valve without being affected by changes in the gas flow or leaks in front of the valve. It is particularly suitable for capillary column diversion, and can maintain a stable pre detection pressure when injecting samples into the divided flow, which is beneficial for separation and improving sensitivity.
