2″-1500LB-SW Full Welded Floating Ball Valve

Technical Data Sheet

Product: 2″ – 1500LB Socket Weld Full Welded Floating Ball Valve
Construction: Full Welded Body

Product Description

This floating ball valve features a full welded body design combined with Class 1500 pressure rating, providing exceptional structural integrity and leak tightness for high‑pressure applications. The fully welded construction eliminates bolted body joints, minimizing potential leak paths and fugitive emissions. Socket weld ends offer permanent, high‑strength connections suitable for demanding service conditions. This valve is ideal for high‑pressure oil & gas, petrochemical, power generation, and critical industrial services.

주요 특징

Full Welded Body

Eliminates bolted flange or bonnet joints, drastically reducing potential leak paths.
Provides superior resistance to external leakage and fugitive emissions.
Enhances structural strength and resistance to pressure surges and thermal cycling.
Compact design with reduced weight compared to bolted counterparts.

High‑Pressure Capability

Class 1500 rating suitable for demanding high‑pressure systems.
Robust wall thickness and welded construction ensure integrity under extreme conditions.

Blow‑out Proof Stem

Stem retained internally; cannot be ejected under pressure, ensuring operational safety.

High‑Performance Seating

Seats available in reinforced PTFE, PEEK, or metal‑seated designs to withstand high pressure and temperature.

Antistatic Device (Optional)

Provides electrical continuity across the valve to prevent static discharge in hazardous environments.

Fire Safe Design (Optional)

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

Dimensions & Weight (Reference)

Final dimensions to be confirmed from certified GA drawings. Bonnet extension height varies with temperature.
