8. 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.
