Inside Blow Out Preventer Arrow Type Check Valve 35~105 MPa, 3 1/16''~9''
Arrow type check valve (drill check valve) is a kind of important inside blowout tool, usually used in the oil and gas drilling and workover. It works with the drilling tool into the well. In the process of drilling and workover in case of overflow, kick, or positive cycle to stop, the arrow type check valve will shut down rapidly under the action of reverse circulation pressure inside drill tools and spring force, cutting the channel within drilling tools, thus play a blowout purpose within drill tools.
