- 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.
