Globe Valves

Globe valves are primarily found in fluid regulation applications. Unlike ball valves, the medium does not flow directly in one direction, but enters the valve body and rises in it before exiting on the other side.

A globe valve is a linear flow valve used to stop, start and regulate flow. The most common application of the globe valve is a standard water faucet, and they are widely used in plant piping.

Globe valves are named for their (semi-)spherical body shape with the two halves of the body. An inner baffle uses to separate the halves. It has a fixed ring seat installed in a spherical body. Shutting the globe valve is achieved by means of a disk, which screws into the seat of the battle by means of a handwheel or actuation. When the handle is turned, the disc is lowered or raised. When the disc is fully lowered, the water supply is shut off. When the disc is fully raised, the water flow is at its maximum rate.

Unlike the gate valve, globe valve can be used for regulating flow or pressures as well as complete shutoff of flow. Compared with a gate valve or ball valve, the globe valve has considerably higher pressure loss in the fully open position. This is because the flow of fluid changes direction as it goes through the valve.

Having the valve seat parallel to the line of flow is an important feature of the globe valve. This feature makes the globe valve efficient when throttling commodities as well as yielding minimal disc and seat erosion.
