Every pressure reducer is traceable: AFKLOK (WOFLY) has upgraded its high-precision flow testing laboratory, achieving a 100% pass rate in factory-wide inspections.

The Airtightness and Precision Flow Testing Center has been fully completed, establishing a mandatory standard for the entire line of pressure regulators: “100% helium mass spectrometry leak testing + laser-marked unique codes for traceability” before shipment, directly addressing the quality control challenges faced by overseas buyers.

To completely address the concerns of industrial gas system integrators and overseas equipment distributors regarding “minor valve leaks” and “hidden defects in batches,” AFKLOK (WOFLY), a leading domestic manufacturer of precision fluid control components, has officially announced that the expansion of its new airtightness and high-precision flow testing center has been completed and the facility is now fully operational.

At the same time, AFKLOK (WOFLY) has made a quality commitment to its global partners: Effective immediately, the company will completely phase out the traditional “sampling inspection” model for its entire lineup of industrial-grade, high-purity specialty gas-grade, and ultra-high-pressure gas pressure regulators, and will officially implement a 100% unit-by-unit final inspection mechanism to ensure that every pressure regulator leaving the factory meets the zero-defect standard. 

Refusing Random Inspections: Building a “Zero Customer Complaints” Supply Chain Firewall for Distributors

In demanding operating conditions—such as specialty gas blending, hydrogen refueling, petrochemical engineering, and semiconductor precursor transportation—even the slightest wear on a pressure regulator seal or an imbalance in gas tightness can lead to costly unplanned downtime or even safety incidents. For overseas distributors, customer complaints and returns that come from across the ocean pose the greatest threat to profits and customer trust.

AFKLOK (WOFLY) fully understands that when overseas distributors are selecting strategic suppliers, what matters most to them is not exaggerated marketing claims, but on-time delivery rates and batch consistency. The head of quality at AFKLOK (WOFLY) stated, We have upgraded our factory sampling inspections to 100% individual performance testing and implemented end-to-end laser marking for traceability—all to provide global buyers with the certainty of products that are ‘ready to use right out of the box and capable of withstanding even the harshest operating conditions. 

Core, High-Performance Configuration: Rigorous Multi-Dimensional Testing Aligned with International Standards

The expanded testing center covers an area of approximately 30 square meters and integrates multiple internationally leading high-precision inspection devices and clean testing production lines:

High-Sensitivity Helium Mass Spectrometer Leak Detector: Performs bidirectional (internal and external) helium leak testing on ultra-high-purity (UHP) and specialty gas regulators made of 316L and 316L EP materials, maintaining a stable and controlled leak rate of ≤1×10−9 mbar⋅L/s, meeting the highest international airtightness standards for comparable high-end products.

Ultrasonic Cleaning and Class 1,000 Cleanroom Assembly: After undergoing multiple stages of degreasing and ultrasonic degassing using ultrapure deionized water, the components are assembled and tested in Class 1,000 and Class 100 cleanbenches to ensure that the tubing and flow channels are free of hydrocarbon and solid particle contaminants. 

                                         Ultrasonic Cleaning Room

High-precision coordinate measuring machine (CMM): Rigorously monitors the microscopic geometric tolerances of the valve body seal seat, dynamically balanced valve disc, and Hastelloy diaphragm to eliminate pressure regulation hysteresis and pressure droop.

Dynamic Pressure Regulation and Pressure Pulse Test Bench: Covers the full operating range from 300 PSI to 6,000+ PSI, simulating extreme intake fluctuations and sustained high-flow surges to verify the regulator’s long-term pressure-holding stability.

One Unit, One Code · End-to-End Compliance Traceability Chain In addition to 100% physical testing, AFKLOK (WOFLY) has simultaneously launched a fully digital, end-to-end quality traceability system:

High-Precision Fiber Laser Marking: Each regulator valve body is laser-engraved with a unique serial number, lot number, rated input/output working pressure, and flow direction markings—data that is scratch-resistant and corrosion-resistant.

Comprehensive compliance documentation: Each shipment includes an EN 10204 3.1 material certificate compliant with European standards (clearly tracing furnace batch numbers, chemical composition, and mechanical properties) as well as a factory test curve report.

Supports OEM/ODM Customized Quality Inspection Standards: We can provide customized helium leak test reports and compatibility pressure test records for specified interfaces (CGA / NPT / JIS / VCR-compatible ferrules) based on customer project requirements.

This comprehensive upgrade of the testing center marks AFKLOK (WOFLY)’s full entry into the top tier of international standards in terms of technical capabilities and quality control systems within the precision fluid control sector, providing global buyers with a preferred alternative to imported products that offers long-term compliance assurance, controllable delivery cycles, and excellent overall value for money.
