Zero Stem Leakage: The bellows seal eliminates external emissions, ensuring a completely sealed environment.
Enhanced Safety: Ideal for handling dangerous, radioactive, or flammable media without the risk of leaks.
Dual Sealing System: Combines bellows and traditional packing for double protection.
Long Bellows Life: Precision-formed multi-ply stainless steel bellows designed for high cycle performance.
Low Maintenance: Virtually maintenance-free operation due to reliable stem sealing.
Environmental Compliance: Supports strict emission and safety regulations (e.g., ISO 15848, TA-Luft).
