Auto-generate control valve lists, safety valve registers, manual valve lists, and equipment schedules directly from P&ID data. Complete specification data (size, rating, material, trim, actuator, fail position, Cv, set pressure, orifice letter, inlet/outlet sizing) extracted automatically and formatted for RFQ, PO, and handover packages. ASME VIII, API 520 / 521 / 526 compliance built-in. Works on any P&ID format including scanned legacy drawings.
In short
Pathnovo's Valve & Equipment List Automation extracts control valves, safety valves (PSV / PRV), manual valves, and equipment (vessels, columns, exchangers, pumps, compressors, tanks, heaters, filters) from P&IDs with full specification: tag, size, end connections, ANSI / ASME body and trim class, body and trim material, trim type (globe, ball, butterfly, rotary, diaphragm), actuator type and sizing, fail position, Cv, rangeability, noise prediction for control valves; set pressure, overpressure, back pressure, orifice letter (D-T per API 526), capacity, inlet / outlet sizing for PSVs. PSV registers structured per ASME Section VIII Division 1 UG-125, API 520 Parts I and II sizing, API 521 scenarios, and API 526 orifice designation, audit-ready for Chief Inspector of Boilers (Indian IBR scope), ASME authorised inspector, and insurance underwriter review. Typical 60 to 100 P&IDs returns 500 to 1,500 valves in 48 hours at 99.5% contractual accuracy, formatted for vendor RFQ (Emerson Fisher, Flowserve, Samson, Metso, Rotork, Crane, Crosby, Farris, Leser) and SAP MM / Oracle iProcurement loading. Revision delta tracking flags replaced valves and re-rated equipment against open POs. Brownfield-ready: extracts from any P&ID format including scanned legacy drawings.
Complete control valve data: tag, body size, end connections, body rating (ANSI / ASME Class), body material, trim material, trim type (globe, ball, butterfly, rotary), actuator type (pneumatic, electric, hydraulic), actuator sizing, fail position, Cv value, rangeability, noise prediction, and P&ID reference, all extracted automatically.
PSV and PRV data with set pressure, overpressure allowance, back pressure (constant and variable), orifice designation (D through T per API 526), capacity, inlet and outlet sizing, body material, applicable code reference (ASME VIII, API 520 sizing, API 521 scenarios). Scenario-based sizing data captured where available.
Gate, globe, ball, butterfly, check, plug, and specialty valves listed with tag, size, rating, material, end connections, and service description. Auto-classification by service (process, utility, drain, vent, sample). Integration with PMS for specification validation.
Equipment tags (vessels, columns, exchangers, pumps, compressors, tanks, heaters, filters) with service description, type, operating conditions, design conditions, material of construction, insulation, and design data extracted from P&IDs and equipment datasheets.
Output formatted for valve vendor RFQ packages (Emerson Fisher, Flowserve, Samson, Metso, Rotork, Crane, Crosby, Farris, Leser, Bailey Birkett, Bopp & Reuther, Sempell) with all specification fields required for quotation. Export to SAP MM, Oracle iProcurement, JDE, or standard Excel / CSV.
PSV register structured per ASME Section VIII Division 1 UG-125 onwards. Sizing methodology per API 520 Part I and Part II. Scenario listing per API 521. Orifice designation per API 526. Audit-ready for pressure vessel inspection and insurance review.
Valve and equipment data consolidated into EPC handover package format for owner-operator ingestion into SAP PM, IBM Maximo, AVEVA NET, or digital twin platforms. See the engineering handover page for the full handover workflow.
Valve and equipment changes tracked across P&ID revisions. Replaced valves, re-rated equipment, deleted items surfaced against open PO status. Integrates with /solutions/procurement-intelligence/pid-revision-po-impact for complete procurement impact analysis.

Pre-commissioning valve check: generate field verification checklists from the valve list
Annual PSV re-certification register for operating facility: inlet / outlet / orifice / set pressure traceability
Convert legacy paper equipment list to digital asset register for SAP PM master data bootstrap
Yes. Pathnovo is an AI tool that extracts valve data from P&IDs automatically: control valves, safety valves (PSV / PRV), and manual valves identified by tag, classified by type, and populated with full specification (size, ASME / ANSI class, body material, trim material, actuator type, Cv, set pressure, orifice letter per API 526). Works on scanned legacy P&IDs, CAD PDFs, and intelligent P&IDs without pre-processing. 99.5% contractual accuracy SLA. Typical 60-100 P&ID set returns 500-1,500 valves in 48 hours, formatted for vendor RFQ (Emerson, Flowserve, Samson, Metso, Rotork) and SAP MM / Oracle iProcurement loading.
For control valves: tag, size, end connections, ASME / ANSI class, body material, trim material, trim type (globe / ball / butterfly / rotary / diaphragm), actuator type (pneumatic / electric / hydraulic / self-actuated), actuator sizing, fail position (fail-open / fail-close / fail-last), Cv value, rangeability, noise prediction, positioner type, and P&ID reference. For PSVs: set pressure, overpressure allowance, back pressure, orifice letter (D-T per API 526), capacity, inlet and outlet sizing, body material, bellows type, applicable code reference. For manual valves: tag, type, size, rating, material, service, and end connection.
Yes. Safety valve registers are structured per ASME Section VIII Division 1 UG-125 pressure relief requirements. Sizing methodology is per API 520 Part I (sizing) and Part II (installation). Scenario listing follows API 521. Orifice designation per API 526. The register is audit-ready for Chief Inspector of Boilers (India, IBR scope), ASME authorised inspector review (USA / international), or insurance underwriter inspection.
Hexagon SPI and AVEVA Instrumentation generate valve lists from their own authored instrumentation databases; they require the valve data to have been authored in the native tool. Pathnovo extracts from any P&ID format including scanned legacy drawings, brownfield revamp drawings, and mid-EPC detailed engineering P&IDs that were never authored in SPI or AVEVA. The output format is interchangeable: Pathnovo can export in SPI-compatible or AVEVA-compatible format for downstream tools.
Yes. Output is formatted for direct RFQ submission to valve vendors: Emerson Fisher, Flowserve, Samson, Metso, Rotork, Crane ChemPharma, Crosby, Farris, Leser, Bailey Birkett, Tyco, Bopp & Reuther, Sempell, and Indian / regional manufacturers (KSB, Audco, Hindustan, IVC, BDK). Each vendor's preferred format template is pre-configured. RFQ packages typically turn around in a single day.
Yes. Brownfield digitisation of handwritten / typed / scanned equipment lists is a common engagement. Pathnovo structures legacy registers with tag, type, service, material, design data, and maintenance history into a live digital register. This typically bootstraps the SAP PM or Maximo equipment master for operating plant digitisation.
A typical process unit (60-100 P&IDs, 500-1,500 valves) is returned as a complete valve list within 48 hours. Large EPC projects (500+ P&IDs, 10,000+ valves) delivered in 1-3 weeks with dedicated capacity. PSV register (100-500 PSVs) typically within 72 hours including API 520 / 521 sizing validation.
Yes. Extracted valve and equipment data feeds SAP PM functional location / equipment master and IBM Maximo asset / location registers via pre-certified connectors. Each valve carries its tag, specification, code reference, maintenance class, and IBR / PESO classification ready for Day 1 operations. See the SAP PM integration detail and the Maximo integration detail for the end-to-end handover pipeline.
