BAOYI power station check valve is a special valve mainly used for thermal power station, and the product design can meet JIS E-101 and ASME standards. Generally, the product is applied as the automatic control equipment for preventing medium backflow in the high-temperature steam devices of the system pipelines for power station, petroleum, chemical product, metallurgy, etc. in high-temperature high-pressure environments.

·Due to the adoption of pressure self-tightening sealing structure for the shell, the sealing property is improved along with pressure rise;
·The sealing surface is overlapped with hard alloy wearing layer through bead welding to resist to wear, high temperature, corrosion and scratch;
·Built-in structure, no external leakage point, and more reliable use.
