  1. Features & Applications
  • Key Features:
    • Zero Leakage Stem Seal: The stainless steel bellows is welded to the stem and bonnet, creating a hermetic seal that eliminates fugitive emissions and prevents product loss.
    • Double Safety: A secondary graphite packing provides backup sealing in the unlikely event of bellows failure, ensuring operational safety.
    • Maintenance-Free Operation: Eliminates the need for regular packing gland adjustments, reducing maintenance costs and downtime.
    • Long Cycle Life: Bellows design is tested for thousands of cycles without fatigue, ideal for frequent operation.
    • Excellent Throttling Capability: Globe valve design provides precise flow control and regulation.
    • Corrosion Resistance: Full stainless steel construction (body, bonnet, bellows) offers superior resistance to corrosive media.
    • TA-Luft / ISO 15848 Compliance: Optional low-emission packing and gaskets meet stringent fugitive emission standards.
    • Backseat Design: Protects bellows and packing when valve is fully open.
  • Main Applications:
    • Thermal Oil Systems & Heat Transfer Fluids: Prevents leakage of high-temperature oils.
    • Steam Systems (Power Plants, Process Industry): Eliminates steam leaks to atmosphere.
    • Chemical & Petrochemical Processing: Handling toxic, hazardous, or corrosive fluids.
    • Pharmaceutical & Food Industry: Sanitary design, prevents contamination.
    • Refineries: Hydrocarbon services requiring zero leakage.
    • High-Purity Applications: Where process contamination must be avoided.
