Cast Steel Gate Valve

The Globe Valves are primarly used to modulate or regulate the volume of the flow.

A Globe Valve is not recommended when a continuous full flow of fluid is required due to the high pressure drop inherent to the design of a Globe Valve.

This type of valve should always be installed so the flow intake enters through the base of the valve seat. The valve has an arrow stamped on the body to indicate the preferred direction on flow.

Globe Valves may be used with fluids containing particles in suspension.
