6 in-depth engineering guides on API 607 — specification, selection, testing and procurement.
Everything on API 607
Vajra's engineering team has published 6 technical guides covering API 607 for industrial valve selection, specification, testing and procurement. Browse the full set below.
Emergency Shutdown (ESD / SDV) Valve Guide: SIL, Partial Stroke & Fail-Safe
Emergency shutdown valves are the final element of a safety instrumented function - they must close on demand, every time, even on fire or power loss. This guide covers fail-safe design, SIL, partial-stroke testing, and selection for ESD service.
Fire-Safe Valve Design - API 607 & API 6FA: What It Means and When It's Required
Fire-safe valves are specifically designed and tested to maintain an acceptable shutoff performance after exposure to a fire and subsequent fire suppression. This guide covers API 607 versus API 6FA testing, fire-safe design features, and when fire-safe certification is mandatory for industrial valves.
Valve Selection for Oil & Gas Upstream Operations
Upstream oil and gas operations demand the highest valve reliability - wellhead blowouts and pipeline failures are catastrophic. This guide covers Christmas tree configurations, NACE sour service requirements, fire-safe testing, and the API 6D compliance framework for upstream valve procurement.
Fire-Safe Ball Valves: API 607 Testing, Metal Seat Secondary Seal & ATEX Certification
A fire-safe valve must maintain acceptable external leakage rates even after all polymeric seats, seals, and packing have been burned away in a 750°C–1000°C flame for 30 minutes. This guide covers API 607 fire test requirements, the burn-out test protocol, metal seat secondary seal design, graphite packing backup, and ATEX/IECEx certification requirements for hazardous area valve actuators.
Fire-Safe Valve Testing - API 607 vs API 6FA Explained
Fire-safe certification is mandatory for valves in hydrocarbon service at refineries, pipelines, LNG terminals, and petrochemical plants. API 607 and API 6FA define the fire test protocols - but they cover different valve types and have different acceptance criteria. This guide explains the test, what it measures, and when each standard applies.
Fire-Safe Valve Design and the API 607 Standard Explained
Fire-safe valves are designed to maintain acceptable leakage rates during and after a fire event, protecting process plants from escalating hydrocarbon releases. This guide covers API 607 and API 6FA test requirements, design features, and specification guidance.
