Dump Valve

During drilling or tripping operations, dump valve moves up under the influence of spring and bypass hole will stay open. At that time, the flow of drilling fluids will pass through the hole or enter into drill string or drill pipe in order to balance the pressure difference between internal and external. While pumping, the drilling fluids will give rise to resistance due to the fact that valve's bore diameter is smaller than the internal diameter of drill. As the resistance is exceeding the spring force, the bypass hole will be blocked and drilling fluids will flow through power section.

DONGCHEN is a professional dump valve manufacturer and supplier in China. We provide a vast array of products, including ladle turret, downhole drilling motor, software hardware automated procedure and more.
