The clamp type check consists of the valve body, valve clack, valve stem and spring. Because of the short closing stroke of the valve and the spring loading, the water hammer can be significantly reduced. The valve is mainly suitable for urban, industrial and high-rise building water supply and drainage pipe network. Since the length of the structure is shorter than that of the conventional check valve, it is most suitable for places where the installation space is limited. The clip type check valve is used for pure pipeline and industrial, environmental protection, water treatment, water supply and drainage pipelines of high-rise buildings, and prevents the reverse flow of medium.

1, The product structure is short in length, small in size and light in weight.
2, The sealing valve can be made of soft or hard sealing material according to different working conditions. The sealing performance is good.
3, Horizontal or vertical pipes can be used, easy installation.
4, The valve closed fast, water hammer pressure is small.
5, Parts, materials and valve end form, size, according to actual conditions or user requirements, reasonable matching, to meet the needs of various projects.
[Valve structure drawing]
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.
