20″-600LB-RF 3-Piece Trunnion Ball Valve Forged

20″ – 600LB – RF 3-Piece Forged Trunnion Ball Valve

Technical Data Sheet

1. General Information

2. Design & Manufacturing Standards

3. Main Materials (Typical – can be customized)

Note: A105 and A105N are the same material; A105N is normalized.

4. Outline Dimensions & Weight

 Dimensions above are typical references. Final dimensions to be confirmed with manufacturer’s drawing.

5. Pressure-Temperature Rating (ASME B16.34 – Carbon Steel Group 1.1)

Data based on ASME B16.34 Material Group 1.1 (A105 / A216 WCB / A350 LF2). Maximum allowable working pressure decreases with increasing temperature. For stainless steel bodies (Group 2.1), pressure-temperature ratings differ.

6. Performance Data

7. Key Design Features

• Trunnion mounted ball – Ball is supported by upper and lower stem bearings; line pressure forces are absorbed by the trunnion bearings, ensuring low operating torque and stable sealing performance, especially for large bore and high pressure applications.
• 3-piece side entry body – Bolted 3-piece construction allows inline maintenance without removing the valve from the pipeline.
• Double block & bleed (DBB) – Upstream and downstream independent seat sealing provides bi-directional shut-off with zero leakage; installation is non-directional.
• Spring-energized seats – Pre-loaded springs maintain seat-to-ball contact even at low pressure, ensuring reliable sealing.
• Automatic cavity pressure relief – When the valve is in the fully open or fully closed position, excess pressure trapped in the body cavity can be relieved by seat retraction, protecting the valve.
• Fire safe design (optional) – If the non-metallic seat is softened or destroyed by fire, the metal sealing surface of the seat support ring contacts the ball to provide secondary metal-to-metal sealing, compliant with API 607 or API 6FA. (API 607 6th Edition now covers the scope formerly addressed by API 6FA.)
• Blow-out proof stem – Stem is designed with anti-blowout retention, ensuring it cannot be accidentally ejected under pressure.
• Anti-static device – A spring-loaded anti-static device provides electrical continuity between the ball, stem, and body, preventing static charge accumulation.
• Emergency sealant injection – Sealant injection fittings are provided on the stem and seat areas; sealant can be injected to temporarily stop leakage in an emergency.
• Full bore design – The valve bore matches the pipeline internal diameter, allowing pipeline pigging with minimal flow resistance.
