Over the last decade Lishui Ouyi Valve has evolved to meet the growing customer demands and maintaining high quality standards, competitive pricing and dedicated after service.

With the API 6D, API 600, API 607/6FA, CE and TS standard certifications, we have set up total QC control system that covers the operation processes right from the inquiry stage till the dispatch leading to total traceability and quality control.

We are also actively developing and improving designing technology based on our customer requests which has led to the company owning quite a lot of product patents.
