4 in × 600# RF trunnion-mounted ball valve, 1,480 psi sour-service per API 6D. ANSI raised-face flanges for gas-processing and pipeline-inlet manifold service.
The Trunnion Ball Valve, 4 in × 600# RF, 1,480 psi, Sour Service is a ball — trunnion ball valve rated for 1,480 psi working pressure with 4 in 600# ANSI Raised-Face Flange inlet and 4 in 600# ANSI Raised-Face Flange outlet. NACE MR0175 / ISO 15156 sour-service compliant — H₂S-rated trim and elastomers.
Working pressure 1,480 psi (ANSI 600 class). Manufactured to API 6D. Service class: Sour (NACE MR0175).
Confirm (a) line pressure rating and pressure class, (b) inlet and outlet end-connection sizes / styles, (c) service class (sour vs standard), (d) bore preference (full vs reduced port), and (e) any temperature, fugitive-emissions, or fire-safe certification requirements. Indus quotes ex-Dubai with full mill test reports, API monogram traceability where applicable, and pre-shipment hydrostatic / shell test certificates.
Pair with matched-pressure check valves, plug valves, and flow-iron unions of the same end-connection family. For wellhead service, also specify gate valves and surface safety valves of the equivalent API 6A pressure class. For frac applications, the 1502, 602, and 206 Weco unions are the most common matched standards.
