How We Handle Details Makes Us Different

The performance, durability, and service life of DBV industrial valves come from how we process and prepare each of our raw materials: properly, with great attention to detail.

Rough Machining

With a 2500mm large vertical lathe and other heavy horizontal lathes, we shape the material into the required workpiece for our industrial valves.

Heat Treating

Metal materials are processed in our heat treatment furnace to improve their microstructure, ensuring the performance of our pump valves can meet our standard requirements.

Surface Finishing

The surface roughness of our industrial parts is controlled by our advanced sandblasting technology, ensuring the roughness value of the surface is within the required range.

Fine Machining

The finishing process of Valve involves the use of CNC machining precision equipment to guarantee all of our industrial valves have the expected quality and stable performance.

Boring Process

Experienced staff utilizes a large-scale CNC horizontal machining center to ensure all workpieces’ dimensions and shapes are accurate to the expected design range.

Drilling

The dimensions, design concept, and shape of our industrial valve workpieces are finely tuned with our large-scale CNC gantry pentahedron machining center.

Growing Attentive Research And Development Culture

Valve focuses on technological innovation, scientific design, and precision manufacturing. Our R&D department is dedicated to designing valves that suit the global market and contribute to industry advancements.

Throughout our developments and testing, we strictly follow quality management standards, ensuring our valves consistently perform at their best.

An Experienced R&D Team for Valve Design

For 15 years, our R&D team has constantly advanced in the design and development of valves, with 7 independently developed products and 10 patents. Among our achievements, we have developed a cryogenic valve last year.
