Ball Valve Trunnion Mounted Class 150/300/600 - 6015/6030/6060 FB | JC Valves

JC Valves Trunnion Mounted Ball Valve FB 6015/6030/6060

Types 6015 / 6030 / 6060 are trunnion mounted, 3-piece forged, full bore ball valves with flanged ends for Class 150 / 300 / 600. The 6000 series differs from cast designs by utilizing a three-piece forged body, suitable for lines with higher pressure, increased cycle demands, and material traceability requirements.

Technical Specifications

Seat Design and Cavity Pressure

Standard construction uses SPE seats. In this configuration, overpressure in the body cavity due to thermal expansion can be relieved to the line. For applications requiring bidirectional sealing, DPE seats are available, requiring external cavity pressure relief. PMSS and emergency seat/stem sealant injection are also options for temporary leakage control until maintenance.

Standards and Applications

Series is referenced to API 6D, PED, MSS SP-55, wetted parts per NACE MR0175 / ISO 15156 and NACE MR0103 / ISO 17945, fire-safe per API 607 / ISO 10497 / API 6FA, fugitive emissions per ISO 15848 / TA-Luft, and ATEX. Typical applications: natural gas, hydrocarbons, tank farms, chemical and petrochemical isolation lines.

FAQ

When is the forged 6000 series selected over the cast 2000 series?
When forged materials, 3-piece body, and enhanced mechanical documentation are required for critical lines.

What data is required for specification?
NPS, Class, body material, seat material, SPE or DPE, NACE requirement, fire-safe, fugitive emissions, ATEX, and actuator type.
