Check valve is designed and produced entirely according to API Space 6A and MR0175 Specifications for Wellhead and Christmas Tree, able to be used interchangeably with corollary equipment at home and abroad that is in line with API Space 6A Standard.
It is mainly used to kill manifold.
The spool and the valve seat sealing surface is of hard surfacing alloy, wear resistant and erosion corrosion, reliable work.
It relies on medium pressure to achieve the metallic seal between valve trim and valve body, and the higher the pressure of medium is, the better the sealing property will be. Pipeline pressure can be bearable always to the inside of valve cavity.
