How to order
Confirm (a) line working pressure and pressure class, (b) inlet and outlet end-connection sizes / styles (5M / 10M / 15M flanges, or other), (c) service class (standard vs sour vs HF), (d) actuator mode for hydraulic variants (FC, FLS, or manual override option), (e) any special trim (Inconel 625, Stellite, F22) or temperature class (PR1 / PR2 / PR2F fire-tested) requirements. Indus quotes ex-works with full mill test reports, sour-service certificates where applicable, and pre-shipment hydrostatic / shell test certificates.
Companion products
Pair with matched-pressure check valves, ball valves, and SSV/ESDs of the same flange class to build a complete wellhead service tree or Christmas tree. For hydraulic-actuated trains, integrate with a hydraulic control panel sized to the dome volumes and intervention timings. Indus also supplies API 6A studs, gaskets (R/RX/BX ring-joint), and instrumentation tap-offs to specification.
