[Valve structure drawing]
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.
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.
