Sliding Ball Check Valve (HQ41X-16)

The HQ41X Sliding Ball Check Valve uses a rubber-coated sphere as its valve disk. The ball rolls up and down on the internal guides with fluid flow, ensuring low pressure loss, quiet closure, and no water hammer.

Key Features

  • Full-port design ensures 50% less head loss than swing check valves
  • Rubber-covered steel ball prevents clogging and ensures bubble-tight seal
  • Can be installed both horizontally and vertically
  • Excellent for sewage, municipal drainage, and submersible pump networks
