Check valve
application
Check valves are used in pipes under pressures between PN1.6~16.0MPa(Class150~2500Lb),working temperatures-196~60℃, They are used in industries include oil, chemistry, pharmaceutical, fertilizer,and power gene-ration to prevent the backward
Products design features
1,The products feature a reasonable structure,reliable seal,good performance and nice modeling.
2,Either soft or hard seal can be selected for the product upon different working conditions.The sealing face is built up with Co-based carbide alloy,leaving a better wearability,corrosion and scrap resistance and a longer duration.
3,The opening pressure is small, and the valve disc can be fully opened under a very small pressure difference.
4,Inside-set bolt-bearing structure reduces leakage and reliable use.
5,PN≥16.0Mpa(class1500),the middle cavity uses a self-tightening sealing structure to have the sealing performance reinforced along with the pressure riseso as to ensure the sealing performance.
6,Different parts materials and different sizes for flange,butt-welding are available for sensible combination according to difterent working facts and customers'requirements.
