Product Technical Data Sheet
Product Name: Flanged Trunnion Ball Valve – Metal Seated
Model / Size: 4″ – 600LB – RF / F316L Body / Trunnion Type / Metal Seat
- Общий
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.

- Функции
- 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. - 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. - 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. - 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. - Blow‑out Proof Stem
Stem is designed with integral backseat and anti‑blowout construction to ensure safety under all operating conditions. - Fire‑Safe Design (Optional)
Secondary graphite seal in case of fire, meeting API 607 / API 6FA requirements. - Anti‑static Device
Continuous electrical path between ball, stem, and body to prevent static charge accumulation. - Emergency Grease Injection
Grease fittings on body and stem allow injection of sealant for temporary emergency sealing. - Cavity Relief
Body cavity pressure relief prevents over‑pressurization due to thermal expansion.
- Optional Features
