The DN series manual ball valve for gas pipelines is a specialized valve used in gas transmission systems, featuring a simple structure, easy operation, and excellent sealing performance. The ball valve is primarily used in pipelines for natural gas, town gas, liquefied petroleum gas, and other gases to cut off or connect the flow of media. This valve adopts either floating or fixed ball design, with full-bore or reduced-bore structures, making it suitable for various pressure and pipe diameter requirements.

main features

Good sealing performance: using polytetrafluoroethylene (PTFE) or metal seals to ensure that the valve can maintain good sealing performance in high pressure or low temperature environment.

Fire protection design: some models have fire protection structure. When a fire occurs, the metal seal can still keep the valve closed after the non-metallic sealing material is burned, preventing gas leakage.

Easy to operate: manual operation, 90 rotation can be achieved to achieve the switch, suitable for frequent opening and closing occasions.

application scenarios

Urban gas transmission and distribution network.

Natural gas filling station (high pressure ball valve).

Industrial gas supply system.
