9650/9660/9670 SERIES Sluice / Gate Valve with Electric / Pneumatic / Hydraulic Actuator


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.

Why a Gate Valve?

Probably the single most important characteristic of a gate valve is the efficiency with which fluid flows through the valve. All valves must control fluid flow, meaning they must stop, regulate or allow fluid to pass through.

For the Majority of industrial and utility services, the conservation of fluid energy as it Moves through piping and valve are critical to efficient fluid control device.

As a result, the seat port or minimum opening through the valve will be smaller than for some other valve types having equivalent flow capacity, such as butterfly or globe. Since the seat port size has a major effect on valve cost, the gate valve has an important advantage in reducing valve capital expenses.
