Manufacturer identity
The catalogue covers products published by Lianggu. This website is operated as an independent distributor enquiry channel, separate from the manufacturer’s corporate website.
Product-specific approval
A certificate shown on a manufacturer image does not establish that every size, material or configuration is covered. Match the certificate scope to the offered valve.
Inspection & release
Agree the inspection plan, documentation and release requirements in the order. Requested records may include drawings, material records or test reports, subject to confirmation.
Document control
The commercial offer should identify the accepted specification, approved deviations and documents included with shipment.
