4″-600LB-RF F316L Metal Seated Trunnion Ball Valve

Product Technical Data Sheet

Product Name: Flanged Trunnion Ball Valve – Metal Seated
Model / Size: 4″ – 600LB – RF / F316L Body / Trunnion Type / Metal Seat

1. 一般的な

This product is a split‑body, trunnion‑mounted ball valve with metal‑to‑metal seating and flanged ends. Designed for high‑pressure, high‑temperature, and abrasive or erosive service conditions. Suitable for applications in oil & gas, refining, petrochemical, power generation, and critical process industries where soft‑seated valves are not applicable.

The metal seat construction provides excellent wear resistance, extended cycle life, and reliable shut‑off under severe operating conditions.

7. 特徴

1. Trunnion Mounted Ball
   The ball is supported by upper and lower stem bearings, reducing operating torque and ensuring stable, smooth operation under high differential pressure.
2. Metal‑to‑Metal Seating
   Ball and seat rings are hardfaced with wear‑resistant alloys (e.g., Stellite, Tungsten Carbide). Suitable for high‑temperature, abrasive, and erosive media, with extended cycle life.
3. Spring‑Energized Seat Design
   Seat rings are spring‑loaded to maintain continuous contact with the ball surface, compensating for thermal expansion and providing consistent sealing across a wide temperature range.
4. Double Piston Effect (DPE) or Single Piston Effect (SPE)
   Seat design options allow for bidirectional sealing or Double Block & Bleed (DBB) functionality, depending on application requirements.
5. Blow‑out Proof Stem
   Stem is designed with integral backseat and anti‑blowout construction to ensure safety under all operating conditions.
6. Fire‑Safe Design (Optional)
   Secondary graphite seal in case of fire, meeting API 607 / API 6FA requirements.
7. Anti‑static Device
   Continuous electrical path between ball, stem, and body to prevent static charge accumulation.
8. Emergency Grease Injection
   Grease fittings on body and stem allow injection of sealant for temporary emergency sealing.
9. Cavity Relief
   Body cavity pressure relief prevents over‑pressurization due to thermal expansion.
