MWD Check Valve
Product Description
The MWD Non-Return Valve is an auxiliary device used in directional drilling processes. It serves multiple functions, including signal transmission, delivering power media to the downhole motor, preventing gas outbursts, stopping the backflow of power media, and facilitating the transfer of drilling rig power. It is primarily used in conjunction with kilometer-level directional drilling rigs.
Product Features:
The joint and rod body are designed as an integral structure and undergo overall quenching and tempering treatment.
High tensile strength and torsional performance:
Tensile Strength ≥ 1035 MPa
Yield Strength ≥ 965 MPa
Excellent toughness: Fully meets the standards of Grade 135 steel.
Superior sealing performance: Stable signal transmission under a pressure environment of 10 MPa.
Scope of Application:
The MWD Check Valve is mainly used in conjunction with center-through-cable drill pipes.
