How it works

A check valve opens automatically under forward flow pressure and closes when flow stops or reverses. The closing mechanism varies by type: swing check uses a hinged disc, lift check uses a vertically lifting plug, dual-plate wafer uses spring-loaded split disc halves, and ball check uses a free-rolling ball.

Spring-assisted designs close faster to prevent water hammer. The correct type must be selected based on installation orientation, flow velocity, and media characteristics.

Typical applications

  • Pump discharge protection
  • Compressor suction and discharge lines
  • Water and wastewater pump stations
  • Oil and gas pipelines and facilities
  • Chemical and process plant protection
  • Fire protection and sprinkler systems
  • Boiler feed protection
  • Preventing cross-contamination between lines

Key features

  • Swing check, lift check, dual-plate wafer, and ball check designs
  • Body materials: cast iron, ductile iron, carbon steel, SS316, bronze, PVC
  • Low-pressure drop designs for pump discharge
  • Spring-assisted closing for vertical installation
  • Screwed BSP/NPT and flanged connections
  • EPDM, NBR, and metal seat options
  • Sizes DN15 to DN600
  • Weighted or spring-loaded disc for fast response
  • Dampened designs to prevent water hammer
