Structural features:
 1. The hydraulically formed bellows forms the first seal to ensure zero leakage of the stem seal.
 2. The multi-stage PTFE packing combination in the stuffing box forms a second seal on the bellows, which increases the reliability of the seal.
 3. The middle flange adopts the groove sealing structure to ensure the reliable sealing of the middle flange even in the case of fluctuation of the pipeline pressure.
 4. The sealing pair matching structure adopts cone and flat type, and the seal is automatically compensated to achieve double insurance effect, stable sealing performance, no adhesive wear and long service life.  

Main parts and materials:

Features:
 1. According to the specific characteristics of the medium, the special bellows valve for chlorine gas is made of corrosion-resistant alloy on the material of the valve body. It is resistant to chlorine gas and liquid chlorine. The low temperature can reach -40 °C, and the working conditions can be guaranteed to the maximum extent.
 2. The hydraulically formed bellows forms the first seal to ensure zero leakage of the stem seal.
 3. The multi-stage PTFE filler combination in the stuffing box forms a second pass on the bellows, which increases the reliability of the seal.
 4. The middle flange adopts the groove sealing structure to ensure the reliable sealing of the middle flange even in the case of fluctuation of the pipeline pressure.
 5. The non-rotating valve stem prevents the bellows from twisting and ensures the service life of the valve for a longer period.
 6. The sealing pair matching structure adopts cone and flat type, and the seal is automatically compensated to achieve double insurance effect, stable sealing performance, no adhesive wear and long service life.
