Tigerrig military quality best price 15000Psi check valve for drilling rig
Production Description：
This product is designed and manufactured in full compliance with the requirements of APISpec6A "Wellhead and Christmas Tree Equipment Specification", and can be matched and interchanged with equipment that meets APISpec6A specifications at home and abroad.
This valve is a check valve. It relies on the pressure of the medium to achieve a metal-to-metal seal between the valve core and the valve body. The greater the medium pressure, the better the sealing performance. The valve cavity can withstand pipeline pressure at any time
This valve body is made of alloy steel forgings, which has strong mechanical properties, can withstand high pressure, and has safe and reliable performance.
The bonnet and the valve body are connected by bolts. The seal is the sealing ring on the bonnet and the inner wall of the valve body. The sealing performance is reliable. It makes the assembly gap between the bonnet and the valve body very small (designed to be 0), thereby reducing corrosion. The medium erodes the bolts and screw holes and reduces the bolt load
The valve core and the sealing surface of the valve body are welded with hard alloy to make them have good wear resistance and corrosion resistance. The valve core material is made of anti-sulfur steel, and the other parts adopt the method of limiting the hardness. Therefore, the valve is in the H2S-containing Use in the environment.
