Product description
The ammonia stop valve is a special valve for non-corrosive gas ammonia and liquid ammonia. The liquid ammonia stop valve is specially designed for ammonia and fuel gas pipelines or devices. Attention has been paid to fire protection requirements on the structure. The packing is made of polytetrafluoroethylene, and the sealing surface of the ammonia gas stop valve is Babbitt alloy seal, the seal is reliable, and the concealed bar design is absolutely no leakage. The sealing material adopts PTFE or nylon to the body material of the valve body, which is a soft seal. It is suitable for ammonia gas and liquefied petroleum gas pipeline system, as an opening and closing device, and also suitable for other pipelines whose temperature is ≤80℃.
Structural features
1. The product structure is reasonable, the sealing is reliable, the performance is excellent, and the appearance is beautiful.
2. The sealing surface is welded with Co-based cemented carbide, which has good wear resistance, corrosion resistance, scratch resistance and long service life.
3. After quenching and tempering and surface nitriding treatment, the valve stem has good corrosion resistance and scratch resistance.
4. The valve is equipped with an inverted sealing structure, and the sealing is reliable.
5. The material and flange size of the parts can be reasonably selected according to actual working conditions or user requirements to meet various engineering needs.
