Check/Non Return Valves

What are Check/Non Return Valves?

Swing Check Valves are non return valves, installed in pressure pipelines, and used to check the reverse flow of liquid by use of a swinging disc inside the fitting. Valves without a lever and weight fitting are only suitable for lower velocities.

Features & Benefits

  • Resilient seated disc
  • Lightweight ductile iron design
  • Pre-fitted extended spindle
  • Durable fusion bonded epoxy coated
  • Highly adaptable lever & weight system
  • Bolt opening for easy maintenance
  • Corrosion resistant construction
  • PN10 and PN16 drillings

Applications

These resilient seated swing check valves are suitable for use with potable water, raw water and sewage, to a maximum working pressure of 16 Bar, and between temperatures of -10°C to +70°C. Insulation is essential for temperatures of 0°C and below.

Ductile iron check non return valve.
