1″-600LB-SW Extended Bonnet Floating Ball Valve

Technical Data Sheet

Full Welded Body · High‑Temperature Service

Product: 1″ – 600LB Socket Weld Extended Bonnet Floating Ball Valve
Construction: Full Welded Body

1. Product Description

This floating ball valve features a full welded body design combined with an extended bonnet for high‑temperature service. The body is completely welded (no bolted joints), minimizing potential leak paths and ensuring superior structural integrity under thermal cycling. The extended bonnet acts as a thermal barrier, protecting the stem packing and actuator from elevated temperatures. Socket weld ends provide a permanent, high‑strength connection.

2. Main Technical Parameters

3. Bill of Materials (Typical for High‑Temperature)

Note: No body gasket is required due to the full welded construction.

4. 主な特徴

1. Full Welded Body

• Eliminates bolted flange or bonnet joints, significantly reducing potential leak paths.
• Provides excellent resistance to external leakage and fugitive emissions.
• Enhances structural strength and resistance to thermal cycling.
• Compact design with lower weight compared to bolted counterparts.

• Lengthened neck dissipates heat, keeping packing area at a lower temperature.
• Protects operator and actuator from heat damage.

• Stem retained internally; cannot be ejected under pressure.

• Seats available in reinforced graphite, PEEK, or full metal‑seated design for elevated temperatures.

• Ensures electrical continuity across the valve.

• Designed per API 607 / ISO 10497; secondary metal‑to‑metal sealing after seat burnout.

5. Dimensions & Weight (Reference)

Extended bonnet length varies with temperature; typical values for service up to 300°C. Final dimensions to be confirmed from certified drawings.

6. Design & Manufacturing Standards

Testing:

• Shell strength test: 1.5 × rated pressure (no visible leakage)
• High‑pressure seat test: 1.1 × rated pressure
• Low‑pressure seat test: 0.6 MPa (for soft‑seated versions)

7. Ordering Information
