Valve Lookup

Valve Lookup is an offline reference for valve face-to-face and centre-to-face dimensions, ASME B16.34 pressure-temperature ratings and valve materials — 413 dimension rows, each traceable to a named public source. Valve Lookup is free to download. Selected globe, control, plug and butterfly dimension lookups are available without a time limit. Paid full access is required for the complete reference catalogue, pressure-temperature ratings, materials, tools and the optional on-device document importer. No purchases take place inside the app. Existing licence keys continue to work. If you update during a trial from an earlier version, its original end date is preserved. Free selection: Class 150 long-pattern flanged globe NPS 1-1/4, 5, 14 and 16; Class 150 short-pattern flanged control NPS 14; Class 150 regular/venturi flanged plug NPS 14; class-independent wafer/lug butterfly NPS 5 and double-flanged butterfly NPS 16. These are selected entries; the free edition does not include every globe valve or size. With full access: - Gate: short pattern Class 150 (NPS 1/2-24) and Class 300 (NPS 2-12 from two sources; NPS 1/2-1-1/2 and NPS 14-24 from one source, marked in the app); long pattern Class 300 (NPS 14-24), Class 600 (NPS 1/2-24), Class 900 and 1500 (NPS 1-24), Class 2500 (NPS 1/2-12). - Globe: long (regular) pattern, Class 150 (NPS 1/2-18), 300 (NPS 1/2-20), 600 (NPS 1/2-12). No short-pattern globe table: no trustworthy public source was found. - Ball: long pattern, Class 150/300/600, NPS 1/2-24. - Butterfly: wafer/lug (ISO 5752 / EN 558-1 series 20) and double flanged (EN 558-1 series 13), NPS 1-1/2-24, class-independent at Class 150 and 300. - Swing check: Class 150 (NPS 1/2-24), 300 (NPS 2-24), 600 (NPS 1/2-24). - Plug: Class 150 (NPS 2-20), 300 and 600 (NPS 2-24), 900 (NPS 2-16); each row labelled with its pattern (short, short/venturi, regular, regular/venturi or venturi). - Control: globe-style face-to-face per ANSI/ISA-75.08.01 — short pattern Class 150 and 300, long pattern Class 600, NPS 1/2-16 — plus angle centre-to-face at Class 150/300/600, NPS 1-8. - ASME B16.34 standard-class pressure-temperature ratings, Class 150 through 2500, for carbon steel WCC, alloy steel WC6 and stainless CF8M and CF3M. A dash means no published rating at that temperature, not a missing number. - Valve materials: body groups with ASTM specs and grades, API trim numbers and seat types. - Two tools: pressure-temperature lookup with published/interpolated markers, and drop-in replacement comparison of face-to-face lengths against your allowed difference. - A source screen naming all 23 public sources, their coverage and access dates. Published millimetre values are retained. Published inch values cover 281 of 413 rows; the rest are converted and marked. Single-source values carry a dagger; unresolved disagreements are withheld. Switch between inch/psi and mm/bar any time. Optionally, open a document you already own on this device: the app reads it here, keeps only the face-to-face numbers it recognises, and uploads nothing. Every value is reference only. Confirm every dimension and rating against the current edition of the standard, the project specification and the manufacturer data sheet that govern your work before you rely on it for design, purchase, fabrication or inspection. Standards get revised; the app does not certify current-edition compliance. This app is not affiliated with, endorsed by or licensed by ASME, API, ISO or ISA, or by any manufacturer or distributor in its source list. They publish the standards; the names describe only what the data covers. No standards text or figure is reproduced. Valve Lookup collects no data. It declares no network permission and makes no calls to us or anyone else. No analytics, no ads, no account, no advertising ID. Your unit preference, licence key, trial dates and record of accepting the Terms stay on your device.

Selected valve lookups are now free without a time limit. The complete reference catalogue and tools remain available with a full-access licence. Keys already purchased continue to work, and any active trial from an earlier version keeps its original end date. Key verification remains offline.
