Check valve is installed in the high pressure pipeline, to prevent fluidbackflow, and the dart automatically closes when the fluid backflow plays a sealing role. The check valve is forged with high strength alloy steel, simple in appearance, and easy to assemble and unassemble in the pipeline. In the case is under great pressure
have longer service life
Design features:
Darts type single valveinstallation direction is not restricted;
installation, disassembly simple;
has certain self-locking;
more suitable for gas seal to the environment.
