A globe valve is a type of valve used for regulating flow in a pipeline, consisting of a movable disk-type element and a stationary ring seat in a generally spherical body.

Globe valves control flow by the vertical movement of a disc away from the seat. This creates an annular space allowing passage of fluid. By adjusting the disc position, the flow rate can be regulated.

Globe valves are primarily used for throttling purposes and where the pressure drop through the valve is not a controlling factor. They are common in applications involving cooling water systems, fuel oil systems, feedwater, steam, chemical feed, and condenser air extraction systems.

A: The key advantages include good shut-off capability, minimal leakage, and the ability to throttle flow. They also offer superior sealing performance and ease of maintenance.

Yes, globe valves are suitable for high-pressure applications. Their robust design and effective shut-off capabilities make them ideal for high-pressure systems.

Yes, globe valves can be used for controlling both liquid and gas flow. They are versatile and can handle various types of fluids.

The primary difference is in their operation and construction. Globe valves are used for regulating flow, while gate valves are used for on/off control. Globe valves have a disc that moves perpendicular to the flow, whereas gate valves have a gate that moves parallel to the flow.

Maintenance involves regular inspection for leaks, periodic cleaning, checking for wear and tear, and ensuring that the stem and disc move freely without extra force.

Globe valves are commonly made from materials like cast iron, stainless steel, bronze, etc depending on their application.

Globe valves are primarily designed for regulating flow, not for changing flow direction. They can, however, stop flow completely when closed.

The choice of a globe valve depends on factors such as the type of fluid, pressure and temperature conditions, flow rate requirements, and whether throttling is needed.

Yes, globe valves can be fitted with actuators for automatic operation, which is particularly useful in large-scale industrial applications where manual control is impractical.
