Integral Bypass Gate Valve

Integral Bypass Gate Valve

Overview

Clover’s resilient seated integral bypass gate valves comply with AS2638.2 for pipeline isolation use in above and below ground pressure water supply and sewerage applications.

Bypass valves are used during the pipeline filling process to reduce the risk of damage to components and to equalize downstream pressure and reducing operating torque.

Key Features

  • High strength and impact resistant body manufactured from ductile iron and EPDM encapsulated gate.
  • Full bore design eliminates any potential debris build up.
  • Integral bypass valves provide a compact footprint and faster installation reducing installation costs.
  • Thermally bonded polymeric coating for long life corrosion protection.
