H2S Resistance Inside Bop Valve , Large Pressure Drop Check Valve, 35 ~ 105 MPa
Inside BOP Tool Large Pressure Drop Check Valve, 35~105 MPa
Inside BOP Valve is a large pressure drop check valve. The tapered plug of valve reduces the cutting action of the mud on the seat to ensure the closed position. Inside BOP Valve connected with drill string can protect swivel, hose and stand pipe. It can also be used before high pressure pump to prevent high pressure blowout.
It is also a releasing tool to make the valve opening usually, and allows the backflow through. This optional release tool is installed in the float valve and the whole assembly is kept ready on the platform for quick installation at the first signs of backflow when drill pipe is pulled out of the well.
We also produce H2S resistance Inside Bop Valves, which adopt high quality import sulfur-resistance material.
