See the certificate. Then verify the scope.
HHSV presents certification evidence by legal entity, validity and actual authorization. For an RFQ, we confirm whether the proposed valve falls inside the applicable scope.
Image-first evidence for technical review.
Upload the current certificate image into each marked Elementor Image Widget. Keep the certificate number, holder, issuing body, validity and scope next to the image so procurement and engineering teams can review both together.
Legal entity
The certificate holder must match the manufacturing and contractual entity.
Product scope
Model, product type, pressure range and marking must cover the proposed supply.
Current validity
Use the current certificate or authorization at the time of technical approval.
Product authorization with the document visible.

Legal entity: Henghua Valve Co., Ltd.
Permitted sub-item: Safety Valve (A, B)
Validity shown: May 12, 2029
Scope: Specific product categories and type-test coverage must be checked against the current license and applicable type-test documentation.
Supplier records should be visible too.
These records demonstrate supplier history. They do not replace project-specific AVL approval, current vendor registration or product certification.
PetroChina
Insert the current PetroChina supplier/network qualification image and confirm project-specific acceptance.
Sinopec
Insert the current Sinopec supplier/network qualification image and confirm project-specific acceptance.
CNOOC
Insert the current CNOOC supplier/network qualification image and confirm project-specific acceptance.
Reserve space for supporting evidence as the library grows.
Use these optional image positions for current CNAS/laboratory evidence, credit or service qualifications, type-test certificates or other project-relevant documents. Rename or remove any slot that is not needed.
Laboratory / CNAS Evidence
Replace with the current supporting document if it is relevant to customer review.
Type-Test Evidence
Use for a current type-test or performance-verification document.
Service / Credit Qualification
Use only when the qualification is current and useful to supplier review.
Other Project Qualification
Reserve for owner-specific or project-relevant evidence.
Keep three statements separate.
Certified to
The supplied product is inside the actual certificate or authorization scope.
Tested in accordance with
A defined test was performed to a standard; this alone is not product certification.
Designed in accordance with
The design follows a standard basis; do not present this statement as certification.
Send the requirement; verify the exact scope.
Provide the valve or service data, applicable project standard and required certificate. HHSV can then confirm the applicable scope and prepare the supporting submittal.
Valve
Series, size, set pressure, service and material.
Requirement
Standard, owner specification, mark and certificate.
Scope check
Entity, factory, model/pressure coverage and validity.
Submittal
Certificate matrix, datasheet, calculation and MDR scope.
Ask for the current document with the RFQ.
We will match the certificate scope to the proposed valve instead of relying on a generic compliance statement.
