John valve has a professional and efficient Research and Development department. We sketch in Autocad for the 2D drawing. In this way our casting foundry can produce according the drawing and our machine shop could also have the standard to machining. We also sketch 3D drawing in Solidwork. We could calculate the weight, metal floating when casting and even the floating rate inside the valve. In order to make our design better.

We could design the product according to customer's demand; we could also measurement according to customer's drawings. In 2008 we have bought a 3D Coordinate Machines, in order to control our product's dimension precisely. Because we want to control each pieces according to the drawing, to make sure the best quality to our customer.

Our professional R&D also could design the new product. They also do the Research, in order to improve our product to make it better. We want to make Johnvalve to make progress every day.
