Vajra Valve Data Commons
Open Machine-Readable Engineering Datasets
The engineering datasets behind this library as downloadable JSON — material-fluid compatibility, grade equivalence, temperature limits, valve standards, the VMI and chloride ranking. Free to use with attribution; built for spreadsheets, research and AI systems.
The Vajra Valve Material Index (VMI)
Materials Ranked by Service Versatility
The VMI — Vajra's benchmark scoring every valve material 0-100 on how many process fluids it handles, and how well, on a transparent methodology computed from real compatibility data. Hastelloy, titanium, duplex, SS 316L and more, tiered Universal to Specialist.
Material Temperature Envelope
Cryogenic to High-Temperature — 40+ Grades
The service-temperature operating window of every common valve material on one chart — carbon steel, stainless, chrome-moly, duplex, nickel alloys and non-ferrous — from −254°C to +1,100°C. ASTM grades with min/max °C, the engineering reference for material selection by temperature.
Material Equivalence Matrix
ASTM ↔ EN/DIN ↔ UNS ↔ BS ↔ JIS
Cross-reference 40+ valve material grades across ASTM, EN/DIN, UNS, BS, JIS and IS standards. Find the European, UNS or Japanese equivalent of A216 WCB, A351 CF8M, A352 LCC, duplex and nickel-alloy grades — the engineering equivalence reference.
Valve Standards Map
API · ASME · ISO · EN · BS · MSS — Cross-Referenced
The whole landscape of industrial valve standards grouped by issuing body and cross-referenced — API 6D, API 598, API 607, ASME B16.34, ISO 5208, NACE MR0175 and 40+ more. See which standard governs design, testing or material, and how they connect.
Chloride Resistance Ranking
Best Materials for Seawater, Brine, Chlorine & HCl
Valve materials ranked by chloride resistance — Hastelloy, titanium, super duplex, duplex 2205, Monel and SS 316L scored across seawater, brine, chlorine, hypochlorite and hydrochloric acid. The first-cut ranking for chloride and seawater material selection.
Valve Trim Selection Guide
Seats · Discs · Stems · Balls · Hard-Facing
How to select valve trim — which grades (13Cr, SS 316, Stellite, duplex, Alloy 625) suit seats, discs, stems and balls, mapped from 40+ valve materials. Match corrosion to the fluid, hardness to the service, stem to the torque.
Valve Service Selection Atlas
Recommended Valve Type & Standard for 50+ Fluids
The recommended valve type, governing standard and typical pressure/temperature for 50+ industrial fluids on one page — sulphuric acid, chlorine, LNG, steam, crude oil, ammonia, slurry and more. The fast 'what valve for this service?' reference.
Standards Applicability Matrix
Which Standard Governs Which Valve Type & Class
The spec-writer's index: which of 50 valve standards govern ball, gate, globe, butterfly, check and plug valves, and at which pressure class. Cite the right standard (API 6D, API 600, API 609, ASME B16.34) on every datasheet and bid.
Material Composition Reference
Chemical Composition of 40+ ASTM Grades
The chemical composition — C, Cr, Ni, Mo and more — of every common valve material grade, from A216 WCB to CF8M, duplex, super duplex and nickel alloys. The metallurgist's one-page valve material chemistry reference, with temperature range and form.
Valve Selection Mistakes
What NOT to Specify — by Fluid
The valves and materials to avoid for each fluid — the costly specification errors that cause seat leaks, corrosion failures and safety incidents. The anti-pattern reference: what not to use for acids, chlorine, seawater, crude and 50+ services.
Valve Type Capability Atlas
Strengths, Limitations & Best Use of Every Type
The strengths, limitations and best applications of every valve type — ball, gate, globe, butterfly, check, plug, needle, diaphragm, safety, control — aggregated from 50+ engineering comparisons. The at-a-glance valve type selection reference.
Industry × Valve Type Matrix
Which Valves Each Industry Uses
The valve types used by each industry — oil & gas, power, chemical, pharma, LNG, marine, mining, water, food — in one coverage grid. Find your sector, see its valve set, and open the application-specific selection guide for each.
Piping Class Quick Reference
Body Material, Rating, P/T & Corrosion Allowance
Every piping class side by side — A1A, B1A, C1A, D1A sour, E1A cryogenic and more — with ASME class, body material, design pressure/temperature, corrosion allowance and fluid service. The piping engineer's one-page class comparison.
Valve Testing Requirements by Standard
Shell · Seat · Fire · Leakage — per Standard
What each standard requires at test — API 598, API 6D, ASME B16.34, API 607 fire, ISO 5208, NACE. Shell 1.5×, seat 1.1×, leakage classes and fire-test criteria in one place. The QC, FAT and third-party-inspection reference.
