[Valve features]
1, The product structure is compact and reasonable, reliable sealing, good performance.
2. The sealing surface is made of alloy steel or hard alloy. The sealing pairs are matched reasonably, and the service life is long.
3, Adopt all kinds of piping flange standard and flange sealing type, to meet the needs of various engineering and user requirements.
4, Its small size, light weight, good processing technology, is one of the development direction of check valve.
[Adaptive condition]
Check valve installed in the pipeline system, the main role is to prevent media backflow, check valve is a kind of pressure on the media to open and close the automatic valve. The clip type check valve applies to nominal pressure PN1.0MPa~42.0MPa and Class150~25000; nominal diameter DN15~1200mm and NPS1/2~48; work temperature -196~+540℃ of various pipelines, used to prevent medium flow back. By choosing different materials, it can be applied to many mediums such as water, steam, oil, nitric acid, acetic acid, strong oxidizing medium and uric acid.
