AXS Series Shut-off Valve

The AXS series shut-off valve is a safety device for gas transmission and distribution systems, specifically designed for gas pressure regulating stations. When system abnormalities cause monitored pressure to reach preset thresholds (over-pressure or under-pressure), the valve automatically cuts off gas flow immediately to ensure safety. It is suitable for natural gas, manufactured gas, liquefied petroleum gas (LPG), and other non-corrosive, pretreated stable gases.
