TECHNICAL RESOURCES
Compare industrial valve selection guides and request model-specific datasheets, drawings and inspection documents. Prepare a clear technical RFQ with KEHUA.
01
Use the product pages as the starting point for range, materials, standards and applications. Request a project-specific datasheet when you have a duty to review.

Review the supplied API, ISO, special-equipment, RoHS and patent records with their certificate numbers and stated scope.

Share your inspection plan, documentation list or delivery requirements with the RFQ so the team can confirm what can be provided for the order.
Start an RFQBEFORE TECHNICAL APPROVAL
Request the proposed model datasheet and drawing for technical review, then agree the inspection and delivery document list in the RFQ. A family catalogue is a starting point; it does not confirm every configuration, service limit or order-specific test result.
Check the offered construction, size and rating combination, design and operating conditions, component materials, end connections, dimensions and actuation. Match these to the project specification; keep unknown fields marked as pending rather than borrowing values from another series.
No. Review the applicable pressure-temperature rating basis, material and offered configuration at the project conditions. A similar designation or flange appearance does not establish an interchangeable valve or an approved substitution.
No. Verify the holder, scope and current status of the relevant certificate separately. Agree the inspection scope, acceptance requirements and traceability of the records required for your model and order; a company certificate is not an individual valve test report.
Identify the published family before requesting the proposed model documents:

SELECTION TO SUPPLIER REVIEW
A catalogue describes a product range; a model datasheet confirms the proposed configuration; an order document package records the agreed inspection and delivery requirements. Use these guides to prepare your review, then ask Wenzhou Kehua Valve Co., Ltd. to confirm the documents applicable to your enquiry.
Review disc movement, permitted installation, pressure loss and pump stop conditions, then prepare a model-specific check valve RFQ.
Read the guideCheck operating and maintenance clearance, position indication and the offered model drawing before choosing a stem arrangement.
Read the guideReview sealing interfaces, trim materials, process conditions and leakage acceptance, then compare the corresponding floating and trunnion series.
Read the guideCompare ball, butterfly and gate valves before specifying the construction, connection and model.
Read the guideCompare WCB, LCB, CF8M and duplex steel; check the medium, temperature and material specification rather than choosing by grade name alone.
Read the guideUse the enquiry template and quotation deviation checks to record service data, dimensions, pressure, connections, actuation and required documents.
Read the guideSeparate company and certificate evidence from model-specific technical data and the inspection records agreed for your order.
Read the guideDistinguish shell and closure tests, define acceptance conditions and match the inspection report to the delivered valve or documented batch.
Read the guideCheck mating dimensions, pipe-end details, material compatibility, installation access and the connection standard before accepting a valve quotation.
Read the guideCompare flange fit, bolt engagement, disc clearance and the model-specific conditions required for any proposed end-of-line duty.
Read the guideReview pressure-temperature limits, the rating standard and flange compatibility before accepting a proposed PN or Class substitution.
Read the guideReview ball support, seat design, operating differential pressure and actuator data against the offered model and service.
Read the guideDefine the required flow passage, pigging and pipe interface instead of approving the valve from the bore label alone.
Read the guideCompare the proposed entry arrangement, maintenance access, seat design and actuation package using model-specific drawings.
Read the guideCheck offset geometry, seat construction, operating duty and test requirements before shortlisting a butterfly valve model.
