Jindex Dart Valves

Jindex dart valves are primarily designed for flow control within open-topped slurry tanks, cells, channels or splitter boxes.

There are numerous variations including self-contained internal valves which are factory calibrated and installed as a single unit and internal valves which have a bolt down seat cage with only a shaft extending to the actuation unit. Both types offer the stability and reliability advantages of head-guiding where the plug is guided into the seat with guide bars set out all around the plug.

A number of sealed versions for pressurized vessels are also available.


Lime, (CaCO3), calcium carbonate is a very common mineral used in many industries.  Lime has two main uses, as a 12-15% slurry called ‘Milk of Lime’ and used a pH modifier or it is calcined and converted into Calcium Oxide (CaO) powder for use in many industries, including cement.

Jindex has now developed a specific Lime Valve to combat Milk of Lime slurry issues.

Designed for tough abrasive and corrosive applications Jindex Knifegate Valves appropriate for many applications including dry and wet slurries for the mining, power, materials handling, water waste water and cement industries.

Our standard designs incorporate many features which provide excellent wear resistance and avoid many of the design deficiencies of traditional knifegate valves.

The Jindex “Flush Seat Design” will eliminate solids compacting in the seat area and jamming the valve, this is a vast improvement over traditional seat designs.

Depending on the actuation requirements we are able to offer manual, pneumatic, hydraulic and electric operation with limit switches, positioners, solenoids and other accessories as required.
