1″-600LB-SW Extended Bonnet Floating Ball Valve
Description
Technical Data Sheet
Full Welded Body · High‑Temperature Service
Product: 1″ – 600LB Socket Weld Extended Bonnet Floating Ball Valve
Construction: Full Welded Body
Model: [To be specified]
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.

4. Key Features
-
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.
-
-
Extended Bonnet for High‑Temperature
-
Lengthened neck dissipates heat, keeping packing area at a lower temperature.
-
Protects operator and actuator from heat damage.
-
-
Blow‑out Proof Stem
-
Stem retained internally; cannot be ejected under pressure.
-
-
High‑Temperature Seating
-
Seats available in reinforced graphite, PEEK, or full metal‑seated design for elevated temperatures.
-
-
Antistatic Device (Optional)
-
Ensures electrical continuity across the valve.
-
-
Fire Safe Design (Optional)
-
Designed per API 607 / ISO 10497; secondary metal‑to‑metal sealing after seat burnout.
-
