Core Certification Package Included with Every Shipment
Carilovalves has built its reputation over 24 years of operation since its founding in 2000 by maintaining rigorous documentation standards for every valve that leaves their Wenzhou manufacturing facility. The certification package accompanying each shipment represents the company’s commitment to transparency and quality assurance that has resulted in 86% of cases solved successfully and 2,415 completed projects for satisfied clients worldwide.
Each shipment from Carilovalves includes the following essential documentation:
- Material Test Certificates (MTC) — Also known as mill test certificates, these documents verify the chemical composition and mechanical properties of all materials used in valve construction, including body materials, ball components, seats, stems, and bolting.
- Hydrostatic Test Reports — Every valve undergoes 100% pressure testing before shipment, with test reports documenting the hold time, test pressure achieved, and pass/fail results for each individual valve.
- Dimensional Inspection Reports — Comprehensive measurements of critical valve dimensions including face-to-face dimensions, flange bolt hole patterns, stem dimensions, and body wall thicknesses confirm compliance with specified tolerances.
- Quality Control Sign-off Sheets — Documentation showing which quality personnel inspected each valve, the date of inspection, and the inspection criteria applied.
International Standard Certifications
Carilovalves maintains certification to multiple internationally recognized standards, and the documentation provided with shipments reflects compliance with these frameworks. Clients can request specific certification documentation based on their project requirements and the regulatory environment in which the valves will be installed.
| Certification Type | Standard Reference | Documentation Provided | Typical Applications |
|---|---|---|---|
| ISO 9001 Quality Management | ISO 9001:2015 | Quality manual excerpt, process control records | General industrial applications, international procurement |
| API 608 Ball Valve Standard | API 608 (3rd Edition) | API compliance declaration, test reports | Oil and gas, petrochemical applications |
| Fire-Safe Testing | API 607, ISO 10497 | Fire test certificates (when applicable) | Critical process applications, flammable service |
| CE Marking Documentation | PED 2014/68/EU | Declaration of conformity, technical file | European market, pressure equipment |
| Material Traceability | EN 10204 3.1 | Mill certificates, heat numbers | High-pressure applications, critical service |
The company’s holistic solutions approach means that documentation can be customized to meet specific project specifications, whether clients require standard commercial documentation or comprehensive packages suitable for nuclear, aerospace, or other high-criticality applications.
Detailed Testing Documentation Standards
Carilovalves implements real-time monitoring throughout the manufacturing process, ensuring that every valve leaving the facility has been subjected to comprehensive testing protocols. This monitoring generates extensive documentation that becomes part of the shipment record.
The hydrostatic testing procedure follows strict protocols that exceed minimum industry requirements:
Each valve is pressure tested at 1.5 times the rated pressure for a minimum hold time of 15 minutes, with leakage measured in accordance with API 598 standards. Shell integrity tests verify the valve body, seats, and seals can withstand the rated pressure without visible leakage or permanent deformation. Test results are recorded for every valve, creating a traceable record that connects the specific valve serial number to its test performance data.
This testing intensity, combined with the company’s state-of-the-art equipment and strict production standards, has helped Carilovalves achieve an impressive track record with 89% client satisfaction rates and $9.5 million in annual transactions.
Material Certification Requirements
For clients specifying particular material grades or requiring material traceability for corrosion resistance, chemical compatibility, or temperature rating compliance, Carilovalves provides detailed material documentation including:
- Chemical Composition Reports — Spectrographic analysis results confirming the exact chemistry of raw materials used in valve body casting, ball manufacturing, and seat material production.
- Mechanical Property Documentation — Tensile strength, yield strength, elongation, and hardness test results from tensile testing of material samples.
- Heat Treatment Records — Documentation of heat treatment processes applied to achieve required hardness, strength, or stress-relief characteristics.
- Impact Testing Results — Charpy V-notch impact test data for materials operating in low-temperature environments or requiring toughness guarantees.
- Positive Material Identification (PMI) — X-ray fluorescence or optical emission spectrometry verification confirming material grades match specifications.
For corrosion-resistant applications, documentation details the specific alloy composition, including chromium, nickel, molybdenum, and carbon content that determines resistance to specific corrosive media. High durability characteristics are documented through accelerated life testing protocols that simulate extended operational timelines.
Third-Party Inspection Options
Carilovalves accommodates third-party inspection requirements through arrangements with internationally recognized inspection agencies. When clients specify witness testing or independent verification, the company coordinates inspection activities and provides all necessary access, documentation, and support.
The third-party inspection documentation options include:
- Witness Testing Coordination — Arranging for client representatives or third-party inspectors to witness hydrostatic testing, functional testing, or other examinations at the manufacturing facility.
- Independent Laboratory Testing — Arranging for specific tests to be conducted by accredited testing laboratories when specialized equipment or certification is required.
- Inspection Certificate Issuance — Coordinating with classification societies such as Lloyd’s Register, Bureau Veritas, or ABS for marine and offshore applications.
- Special Inspector Appointments — Accommodating specific inspector appointments when clients have established relationships with particular inspection personnel.
