PriceList for Variable Diameter Stabilizer - Arrow Check Valve – LUQI Detail:

Arrow check valve (drilling tool check valve) is an important tool used in drilling and workover of oil and gas.It works with the drilling tool in the well. Once the reverse flow, kick or positive circulation stops in the drilling or workover process, the arrow check valve closes rapidly under the action of the spring force of the back circulation press inside the drill tool, which truncates the internal passage of the drill tool and plays the purpose of blowout prevention inside the drill tool.
