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.
RAW MATERIAL
Carefully selecting steel, we shape the materials into workpieces required for industrial valves.
1
FORGING
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.
2
HEAT TREATED
The precision machining process includes the use of precision machining equipment to ensure that all of our industrial valves have the expected quality and stable performance
3
MACHINING
Experienced employees carry out processing to ensure that the dimensions and shapes of all workpieces are accurate to the expected design range.
4
MARKING
Our CNC pentahedral machining center has made minor adjustments to the dimensions, design concepts, and shapes of industrial valve workpieces.
5
FINAL INSPECTION
We inspect the quality, size, and shape of each component. Ensure that each one meets international standards
