API Valves

What Are API Valves?
API valves are industrial pipeline valves designed and manufactured with reference to API (American Petroleum Institute) standards, primarily for oil, gas, petrochemical and power generation service. The API designation means the valve design, material selection, pressure-temperature ratings, face-to-face dimensions, end connections and test procedures follow recognised API specifications such as API 600, API 608, API 6D, API 598 and ASME B16.34.
API valves are commonly specified in projects where procurement standards require API compliance documentation, where the service involves flammable, high-pressure or critical media, or where project owners and EPC contractors prefer API-referenced designs for consistent engineering, inspection and quality assurance across global supply chains.

API Valve Types Available from Honiks
Honiks is a factory-backed industrial valve supplier in China. We work with a network of qualified partner factories to supply the following API valve types:

API Cast Steel Gate Valves: HN100 — Class 150–2500, NPS 2–48 depending on pressure class and configuration; RF/BW/RTJ options and API 600/API 6D design references apply according to the offered configuration.
Pressure Seal Gate Valves: HN101 — Class 900/1500/2500, NPS 2–36 depending on pressure class and configuration; RF/BW/RTJ options are project-dependent.
API Cast Steel Globe Valves: HN102 — Class 150–2500, NPS 1/2–24 depending on pressure class and configuration; RF/BW/RTJ options and BS 1873/ASME B16.34 references apply where applicable.
Pressure Seal Globe Valves: HN103 — Class 900/1500/2500, NPS 2–12 depending on pressure class and configuration; RF/BW/RTJ options are project-dependent.
API Swing Check Valves: HN104 — Class 150–2500, NPS 2–36 depending on pressure class and configuration; swing-type disc, RF/BW/RTJ options and BS 1868/API 6D references apply according to the offered configuration.
API Floating Ball Valves: HN105 — Class 150/300/600, NPS 1/2–12 depending on pressure class and configuration; floating-ball, RF/BW, fire-safe and anti-static options are project-dependent.
API Fixed Ball Valves: HN106 — Class 150–2500, NPS 2–48 depending on pressure class and configuration; trunnion-mounted, RF/BW/RTJ, fire-safe and anti-static references are project-dependent.

These are current catalog references; size, pressure class, material, end connection and applicable standard remain model- and configuration-dependent and must be confirmed against the product page and approved project documents.

Common Standards
API valves from Honiks are supplied with reference to the following API and ASME standards:

API 600 — Steel gate valves, flanged and butt-welding ends
API 608 — Metal ball valves, flanged, threaded and welding ends
API 6D — Pipeline valves (gate, ball, check)
API 598 — Valve inspection and testing
ASME B16.34 — Valves — flanged, threaded and welding end

Pressure Classes and End Connections
Across the current API product group, catalog reference pressure classes span Class 150 through Class 2500, but the range is not common to every model. End-connection options are model-specific and may include raised face (RF), butt-weld (BW) and/or ring type joint (RTJ); HN105 currently lists RF and BW. Confirm size, pressure class, material, end connection and applicable pressure-temperature rating for the offered configuration against the product page, approved drawing and project specification.

Materials and Project Documentation
Standard body materials include carbon steel (A216-WCB), Cr-Mo alloy steel (A217-WC6) and low-temperature carbon steel (A352-LCB). Stainless steel options are available for selected valve types. Honiks can coordinate material certification, NDE reports, third-party inspection and API-compliant project documentation according to project requirements.
