Product Description:

Double plate, spring loaded design to protect gas or liquid
piping system
Industry standards: ASME B16.1, B16.5, B16.24, B16.34, B16.47, and B31.1

Main Features of Dual Plate Check Valve

  • The double plate check valve has a two spring loaded plate design to open to release medium and bounce back to prevent external leakage. This effective check valve can be installed from any location, providing a tight seal and guaranteed no pressure loss.
  • Two valve plates are fixed to the valve body along a pivot axis, and two springs are installed on the butterfly plate above the sealing surface
  • Under the push of the medium flow pressure, the spring is pressed, forcing the butterfly plate to open. When the medium is reversed, the spring forces the valve to close
  • Such valves can be assembled in horizontal and vertical lines. The sealing surface of the disc and seat is made of alloy steel or hard alloy. With high temperature resistance, corrosion resistance, wear resistance, long service life characteristics.
  • The valve adopts the overall structure, simple and compact, small impact force when closing, small water hammer pressure, high reliability.
  • The valve body adopts no stop ring and no dew point structure, and the shell sealing performance is more reliable.
