Check Valve

详情

Check valves are used in pipes under pressures between PN1.6~*6.0MPa(Class**0~***0Lb),working temperatures***6~*0°C,They are used in industries include oil, chemistry,pharmaceutical,fertilizer,and power generation to prevent the backward flux of the media.

The main structure features include：
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 buit up with Co-based carbide alloy,leaving a better wearability,corrosion and scrap resistance and a longer duration.
3、Small opening pressure,the disc can be opened fully with a very small pressure differential.
4、Inside-set bolt-bearing structure reduces leakage and reliable use.
5、PN≥*6.0MPa（Class***0）,the middle cavity uses a self-tightening sealing structure to have the sealing performance reinforced along with the pressure rise so as to ensure the sealing performance.
6、Differnt parts materials and different sizes for flange ,butt-welding are available for sensible combination according to different working facts and customers' requirements.
