Valve Factory Test Report Sample: A Complete Guide

When purchasing industrial valves such as gate valves, ball valves, globe valves, or check valves, buyers often request a Factory Test Report (also known as an Inspection Certificate or Test Certificate). This document ensures that the supplied valves comply with international standards such as API 598, API 600, or API 6D.

In this article, we will explain what a valve test report includes and provide a sample format that manufacturers and buyers can use as a reference.

What is a Valve Test Report?

A valve factory test report is an official document prepared by the manufacturer’s quality control (QC) department.
It summarizes the inspection and testing results carried out before shipment, proving that the valve meets the required specifications.

This report is usually issued together with:

• Material Test Certificates (MTC, EN 10204 3.1/3.2)

• Manufacturer’s Certificate of Conformity (CoC)

• Packing List and Nameplate Verification

Key Contents of a Valve Test Report

A standard valve inspection report usually contains the following sections:

1. General Information

   • Manufacturer

   • Customer / PO Number

   • Valve Type and Standard (e.g., Gate Valve API 600)

   • Size and Pressure Rating

   • Material (Body, Trim, Seat)

   • Serial Number / Quantity

   • Date of Test

2. Test Items and Results

   • Visual Inspection

   • Dimensional Check (ASME B16.5, API standards)

   • Hydrostatic Shell Test

   • Hydrostatic Seat Test

   • Low-Pressure Air Test

   • Functional Operation Test

   • Marking & Coating Check

3. Conclusion

   • Confirmation that the valve passed all tests

Final Thoughts

A valve factory test report is an essential document in the global valve supply chain. It ensures that valves delivered to refineries, petrochemical plants, power stations, and water treatment facilities are safe, reliable, and compliant with international standards.

Manufacturers can use the sample format above to prepare their inspection certificates, while buyers can request such reports as part of their quality control process.

If you are a valve buyer or EPC contractor, always make sure your suppliers provide a complete valve test report with every shipment.
