One advantage of Gate Valves is their low resistance to flow, which minimizes pressure drop across the valve.

Gate Valves can be used in liquid or gas services to isolate the downstream line from the upstream. Typical applications are in CO boiler outlet lines, expander outlet and electrostatic precipitator lines. They can handle either fluid or gas carrying solids in suspension.

The body of the valve is usually made of SA 516 Gr70 carbon steel (lined with refractory material, in the cold wall design) or 304H stainless steel (for hot wall conditions). Gate valves are capable of operating at temperatures up to 950
