Structural features:
1. The corrugated tube formed by hydraulic molding forms the first seal, ensuring zero leakage of the valve stem seal.
2. The multi-stage PTFE packing combination in the packing box forms a second seal on top of the corrugated pipe, increasing the reliability of the seal.
3. The middle flange adopts a groove sealing structure, which ensures reliable sealing of the middle flange even in the case of pipeline pressure fluctuations.
4. The paired structure of the sealing pair adopts cone and plane types, with automatic sealing compensation to achieve a dual safety effect, stable sealing performance, no adhesive wear, and long service life.
Main component materials:

Product Features:
1. According to the specific characteristics of the medium, corrosion-resistant alloys are selected for the valve body material of the chlorine gas specific corrugated pipe globe valve, which is resistant to chlorine gas and liquid chlorine corrosion. The low temperature can reach -40 ℃, ensuring the maximum use requirements under working conditions.
2. The corrugated tube formed by hydraulic molding forms the first seal, ensuring zero leakage of the valve stem seal.
3. The multi-stage PTFE packing combination in the packing box forms a second channel above the corrugated tube, increasing the reliability of the seal.
4. The middle flange adopts a mortise and tenon sealing structure, which ensures reliable sealing of the middle flange even under pressure fluctuations in the pipeline.
5. The non rotating valve stem prevents the bellows from twisting, ensuring a longer service life of the valve.
6. The sealing pair adopts a conical and planar structure, with automatic sealing compensation to achieve a dual safety effect. The sealing performance is stable, without adhesive wear, and has a long service life.
