Valves QC Inspection
Veriquality provide highly experienced mechanical inspectors to perform testing and quality checks of valves around Asia. We offer a comprehensive range of inspection services which we tailor to meet the requirements of individual clients.
Why Quality Control Is So Critical
for Valves Imported from Asia?
Media flow and hydraulic processes are heavily dependent on the quality and performance of valves. Failures in a piping system caused by faulty or malfunctioning valves can incur significant and costly damages. In some cases, these valve failures may even risk catastrophic property damage, as well as injury or death to workers. Because of the critical role valves have in complex and intricate processes, proper inspecting and testing before shipment should an essential part of a risk mitigation plan in global supply chain.

How Do We Conduct QC Inspection for Valves: Simple Checklist
So how do we perform quality inspections on valves? Veriquality inspectors not only verify the mass production craftmanship and finishing of your valves against your Acceptable Quality Limits (AQL), but also conduct on-site tests to evaluate their mechanical and physical properties, as well as compliance with relevant regulations and your valve quality standards.
Appearance & Surface
Check for scratches, deformation, cracks, burrs, dents, rust, or coating defects.
Threads & Dimensions
Inspect threads for misalignment or damage, ensure all dimensions meet drawings and industry standards.
Sealing Integrity
Examine sealing area for wear, scratches, or pits; use soap bubble or gauge to detect leaks.
Function & Operation
Test open/close for multi cycles to check smoothness, no jamming or improper positioning and evaluate consistent performance.
Performance
Perform pressure test (air/hydrostatis) for shell, seat, backseats to verify no leakage under rated pressure.
Marking & Assembly
Confirm correct labeling, model, and material; verify proper assembly of components including bonnet, stem, handle and actuator.
Main Onsite Tests We Perform for Valves Inspection
onsite tests • instant reporting
Positive Material Identification (PMI) testing for valves is a quick on-site non-destructive inspection. Using portable analyzers, we verify the material grade of valve bodies, stems, flanges and fasteners to confirm they meet required specifications, avoiding material mix-up and ensuring safety and performance.
NDT (Non-Destructive Testing) for valves is a set of on-site inspections used to detect surface and internal flaws without damaging the product. Common methods include PT, MT, UT, and RT, helping identify cracks, porosity, incomplete fusion or other defects in valve bodies, seats and welds, ensuring structural integrity, pressure resistance and safe operation.
Pressure (Leakage) testing for valves is an on-site functional inspection that verifies sealing performance under specified pressure. We apply air or water pressure to check for external body leaks and internal seat leakage, ensuring valves meet tightness requirements and perform reliably under working conditions.
Flow check for valves is an on-site functional test that verifies smooth operation and correct flow control. Inspectors test opening, closing and throttling actions to ensure unobstructed flow, proper sealing, and stable performance under operating conditions.
We check nameplates, technical drawings, material certificates, test reports, and compliance records to confirm document consistency and compliance with valve specifications, industry standards, and customer requirements, ensuring traceability and quality accountability.

Valves QC FAQS
1. What is included in a standard valve inspection?
2. What standards do you follow for valve inspection?
3. How long does a valve inspection take?
4. How many days in advance should I book the inspection?
While next-day inspections are possible where our inspectors are located, we recommend booking at least three business days in advance. Early booking ensures proper scheduling and adequate preparation for the inspection.
5. What is the cost of valves quality control services?
For valves inspection in China, our service fee starts at USD220/man-day all inclusive for most manufacturing hubs. For valves QC services in India, Bangladesh, Vietnam, Pakistan, Pakistan, Myanmar, Indonesia, Phillipines, Cambodia, our service fee is US$200/man-day plus travel costs ranging from US$20 to US$50 in most cases.
6. Do you provide QC services for small-batch valves orders?
Absolutely! We recommend QC inspection on every shipment because even failure of a single piece may cause significant loss or harm to workers.
7. What happens if my products fail the QC test?
With our comprehensive and photo-included reports, you can make the decision on whether to accept or reject the goods; or request the factory to rework the batch. A followup re-inspection would be recommended after rework if the initial inspection inspection fails.
8. Which NDT methods are commonly used for valve inspection?
