The Arrow Type Check Valve, installed between drill stem and bit, is for preventing drilling fluid backflow from the bottom. The body is a crossover sub in which the other parts are installed. When backflow occurrs, the Arrow will press to valve seat so that the fluid can not flow upwards through the valve. When Arrow falls on the down seat, the circulating of drilling fluid can flow through the valve without pressure loss.


When ordering, please specify:
1. Outer Diameter
