- Main Design Features
- بناء الجسم: 2-piece split forged body, side-entry design, bolted body connection.
- Manufacturing Process: Die forged construction, dense grain structure, eliminates casting defects, high strength, suitable for high pressure.
- Ball Design: Floating ball design, ball supported by two seats, media pressure pushes ball against downstream seat to achieve sealing.
- جهاز مضاد للكهرباء الساكنة: Spring-loaded anti-static device between stem and ball ensures static electricity dissipation.
- Blow-Out Proof Stem: Stem designed with blow-out proof feature for safety.
- Fire-Safe Design: Designed to meet API 607/6FA fire test requirements.
- Low Emission Packing: Flexible graphite packing, optional VOC sealing rings to meet ISO 15848-1 fugitive emission requirements.
- ISO 5211 Mounting Pad: Top flange conforms to ISO 5211 for easy actuator mounting.
