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 knifegates.  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.

The Jindex design will provide:

  • Superior Seat Life
  • Superior Packing Life
  • Elimination of valve jamming

A variety of stuffing box packings are available along with body and actuator materials for corrosive atmospheres
