Home / Products / Sluice / Gate Valve /Pneumatic Cylinder Operated Sluice / Gate Valve /9660 Series

Many types of valves have been invented by man to control the flow of fluids. Of those which have survived the test of time, each has at least several features which are unique or important. One offers tight shut-off, another low cost, others effective control of the fluid flow, still others, perhaps combinations of these, and on and on. To date, however, no valve inventor has discovered the ideal valve which combines all these features into one package and experience teaches us that it is unlikely anyone will.

Thus, valve designers have created the globe, plug, ball, gate and numerous other valve types, all of which are in extensive use throughout the world's vast and industrial processes. The gate valve is among the most common because it offers several advantages of function and cost effectiveness over other types. The Cast Steel Gate Valve has been tailored especially for the high pressure, high temperature water and steam services common to many electric utility, industrial and petrochemical applications. It offers all the advantages inherent in the wedge gate concept plus several novel design features.

Features

  • Combination of excellent design features of reputed overseas valve brands
  • Rigid and sturdy design with minimum loss of head across the valve
  • Perfect interchangeability of components
  • Assured parallelism between wedge faces
  • Perfect machining and pressing of body and wedge rings
  • Excellent finish on spindle threads resulting in low friction and smooth operation of valves
  • Long service life and leak-tightness even after thousands of open / close cycles.

Epoxy coating of valves

In considering the seriousness of corrosion due to water, effluent, sea water constituents in the atmosphere and corrosion due to soil and in the wide chemical industry. The bodies' bonnets, key caps and hand wheels of the Sluice / Gate Valve are being protected with fusion bonded epoxy which is electrostatic ally applied epoxy resin coated type on both internal and external surface. This superior coating process offers good corrosion resistance and long operational life.

Direction of Closure

All Sluice Valve and Gate Valve are closed in clockwise direction. Sluice Valve and Gate Valve that close in the anticlockwise direction are also available. The closing direction of wedge is being marked using an arrow on each Valve's bonnet nut for easy identifications during plant/system operation.
