  JIS 10K Type - Cast Iron F Type Swing Check Valve (JIS B 2031)

  TOYO VALVE

  A FC200 main body material cast iron F type swing check valve.
  
  [Features]
  · Suppresses water hammer increasing the disc closing speed and improves the sealing performance by setting the counterweight in the Closed moment position.
  · The opening and closing of the disc is performed more smoothly and the flow of the low-voltage fluid is accelerated by setting the counterweight in the Open moment position and maintaining the balance with the disc.
  · The inner structure of the swing check valve with a counterweight is simpler compared to other shock absorbing reverse valves. Therefore, there are fewer blockages caused by contaminants.
  · The swing check valve with a counterweight enables both horizontal and vertical pipe connections.
