  • Product Description
  • Detailed parameters
  • Micro resistance slow closing check valve, also known as the check valve, its role is to prevent the backflow of the medium in the pipeline. The opening and closing parts are opened or closed by the medium flow and power to prevent the medium from flowing back to the valve called check valve. The check valve belongs to the automatic valve category, mainly used for the medium one-way flow of the pipeline, only allows the medium to flow in one direction to prevent accidents. Suitable for cleaning medium, not for medium containing solid particles and viscosity.

    Micro-resistance slow closing check valve structure characteristics;

    1, the structure length is short, the structure length is only 1/4~1/8 of the traditional flange check valve

    2, small size, light weight, its weight is only the traditional micro-resistance slow-closing check valve 1/4~1/20

    3. The disc closes quickly and the water hammer pressure is small

    4. Horizontal or vertical pipes can be used, easy to install

    5. Smooth flow channel and small fluid resistance

    6. Sensitive action and good sealing performance

    7, the valve stroke is short, close the valve impact force is small

    8, the overall structure, simple and compact, beautiful shape

    9. Long service life and high reliability

    Micro resistance slow closing check valve is mainly composed of valve body, valve cover, valve plate, balance weight, piston and regulating valve. It is used for water supply and drainage pipeline and is installed at the outlet of water pump to prevent medium backflow and fire destructive water hammer. It has the advantages of light disc, large opening, significant power saving effect, low fluid resistance, reasonable water hammer elimination structure, reliable sealing performance, wear resistance, long service life, stable operation, no vibration, no noise, etc. Widely used in clean water, sewage, sea water and other media on the drainage, can prevent the backflow of the medium, but also can effectively destroy the water hammer, to ensure the safety of the pipeline.
