| Quality Management |
Documented quality procedures, inspection records, corrective-action processes, and controlled production documentation. |
ISO 9001 certification issued by an accredited certification body; internal audit and nonconformance records. |
Shows that quality control is managed as a repeatable system rather than relying only on final inspection. |
Very High |
| Product Design Compliance |
Valve design, pressure-temperature ratings, materials, dimensions, and end connections matched to the project specification. |
Applicable requirements may include ASME B16.34, API 6D, EN 12516, or the purchaser’s stated specification. |
Reduces the risk of dimensional incompatibility, rating errors, and unsafe operation in the intended service. |
Very High |
| Pressure and Functional Testing |
Shell tests, seat tests, leakage limits, test medium, test duration, and calibrated test equipment. |
API 598 or ISO 5208 test procedures, supported by signed inspection and test records. |
Provides objective evidence that the valve has been tested for pressure integrity and required shutoff performance. |
Very High |
| Material Traceability |
Heat numbers, component identification, material grades, and traceable links between raw materials and finished valves. |
EN 10204 Type 3.1 inspection certificates, material test reports, and component traceability records. |
Helps verify that pressure-retaining parts match the approved material specification and service conditions. |
Very High |
| Materials for Corrosive Service |
Material selection, hardness control, heat treatment, and compatibility with sour or corrosive environments. |
NACE MR0175/ISO 15156 where applicable; approved material certificates and hardness records. |
Supports resistance to sulfide stress cracking and other service-related material failures when the standard applies. |
High |
| Inspection and Documentation |
Availability, accuracy, and completeness of drawings, datasheets, inspection plans, test reports, and final dossiers. |
Approved inspection and test plan, quality dossier, dimensional reports, coating records, and certificates of conformity. |
Clear documentation simplifies project approval, customs processing, installation, and future maintenance. |
High |
| Delivery Reliability |
Confirmed lead time, production milestones, order status updates, packaging controls, and export readiness. |
Written delivery schedule, production progress reports, packing lists, export documents, and shipment records. |
Reduces project delays caused by unclear schedules, incomplete shipments, or inadequate export preparation. |
High |
| Global Communication |
Ability to interpret international specifications, communicate technical deviations, and respond with clear commercial documentation. |
Approved technical submittals, deviation lists, drawing registers, documented correspondence, and multilingual support where required. |
Prevents misunderstandings between engineering, procurement, inspection, logistics, and end-user teams. |
Medium–High |
| After-Sales Support |
Availability of spare parts, maintenance instructions, warranty terms, technical troubleshooting, and service response procedures. |
Operation and maintenance manuals, spare-parts lists, warranty conditions, and documented service channels. |
Improves maintainability and helps reduce downtime throughout the valve’s operating life. |
Medium–High |
| Ethical and Commercial Transparency |
Clear scope of supply, truthful specifications, transparent exclusions, realistic lead times, and formal handling of changes or claims. |
Detailed quotations, signed purchase documents, change-control records, warranty clauses, and verifiable compliance declarations. |
Builds confidence that commercial commitments and technical statements can be audited and relied upon. |
