Valves

Check Valves Code 11

The Conflow Code 11 - Check Valve is fitted into pipelines on systems where the flow of fluid is required in one direction only.

The design is such that only the weight of the valve component needs to be overcome in the direction of fluid flow and hence the resistance across the unit is small. If system requirements necessitate the valve to be fitted vertically, then a light spring can be added.

The valve is suitable for both hydraulic and pneumatic systems and is designed especially for silent operation on equipment with pulsating or reverberating action (e.g. air compressors).

Typical Applications

  • On water dust suppression systems on mineral cutting machines to keep the pipelines "charged" with water so that the spray heads energise instantaneously when the supply valve is next turned on
