Inert Gas Protection System

The HY139 micro-pressure valve is a spring-set, direct-acting micro-pressure nitrogen sealing valve. It reduces high-pressure gas to very low pressure in a single throttling step and is designed for downstream control only. Suitable for micro-pressure control of various gases, it is particularly ideal for micro-pressure nitrogen sealing systems. Minimum control pressure: 0.3KPa; Maximum control pressure: 15 kPa; Minimum operating temperature: -48°C; Maximum operating temperature: 120°C. Applicable to storage tanks and vessels requiring nitrogen sealing. Additionally, nitrogen sealing regulating valves can be provided to intelligently adjust nitrogen flow based on parameters such as oxygen concentration, material inflow/outflow rates, and pressure.
