We can supply a wide range of butterfly valves, gate valves, globe valves, check valves, ball valves, safety & relief valves, plug valve, forged steel valve, strainers, hydraulic control valves, and pressure reducing valves.
Ningbo Valve Factory was founded as a valve manufacturer in 1959, Geographically, it is located in Ningbo, a seaport at the Delta area of Yangtze River, East China Sea. It takes us around 15 minutes by flight or 3 hours by bus from Shanghai to Ningbo. Company now covers an area over 30, 000 square meters and there are around 250 people at work.
Valve production and design
For decades we have been exploring our own valve engineering and learning other new techniques and designs in use we discovered all over the world, so far, we have succeeded a lot, some valves manufactured in our company have already equaled even exceeded the technical standard in western industrialized countries. To make sure product quality and delivery, we give tight control to the whole valve production from material selection, primary processing such as forging and casting, heat treatment, forming and so forth to final finishing processes.
How are we working with overseas customers?
We are committed to supply outstanding and professional services directly to intended customers all around the world, to delight our customers through our promise to continuous improvement in the design, engineering, and manufacture of products that set the standard for quality and value, we let partner gain from trade with NVF in the long run.
1. We are producing mechanical valves according to CAD or real sample provided by customers.
2. We design mechanical valves for customers who are able to tell us the specific application of the valves or standard that the valve should follow.
3. Selecting those valve carried in this showroom or on our website.
