Product Details

DESCRIPTION:

BS1868 standard horizontal installation full bore flanged cast steel full opening disc swing check valve has the characteristics of large circulation capacity. Its valve flap rotates around the rotating shaft, and its fluid resistance is generally smaller than that of the lift check valve. It is horizontally installed on the pipeline. The swing-type check valve is suitable for larger diameters pipelines. It has four forms to choose from, which are full bore check valve, retainer check valve, small size check valve, socket welded check valve and straight check valve.

FEATURES:

  • The built-in rocker arm swing structure is adopted, and all the opening and closing parts are installed inside the valve body without penetrating the valve body.

  • The connection between the rocker arm and the valve flap adopts a spherical connection structure, so that the valve flap has a certain degree of freedom and has appropriate micro position compensation.

  • It has less resistance to fluid and strong corrosion resistance. It can not only remove the valve body from the pipe, but also open the bonnet for internal inspection and maintenance.
