KR thermal recovery wellhead & X-mas tree is mainly used in wells using steam stimulation or other thermal recovery methods.
Valve body, valve cover, valve plate, valve stem and so on are made of materials with good high temperature creep resistance, the valves can operate at temperature up to 370 °C (698° F) and open or close under high pressure and high temperature without any deformation. Even at 370°C, the seal rings can still maintain good sealing performance.
