What type of valves are commonly used for isolating and throttling in engineering spaces?

Globe valves are commonly used for isolating and throttling applications due to their design, which allows for precise control of fluid flow. The internal structure of a globe valve consists of a movable disk or plug that can be raised or lowered in relation to a seat, enabling it to restrict or allow flow effectively. This design makes globe valves particularly suitable for applications where flow regulation is critical, as they can maintain a steady flow rate even at varying pressure conditions.

Additionally, the versatility of globe valves in handling different types of fluids and their ability to withstand high pressures and temperatures make them a preferred choice in engineering spaces where specific flow characteristics must be maintained. This level of control is essential in processes such as cooling systems, chemical processing, and water distribution systems, where not just isolation but also modulation of flow is necessary for operational efficiency.

In contrast, other valve types like check valves are primarily used for preventing backflow rather than controlling flow, while plug and butterfly valves, though useful in certain isolating applications, do not offer the same level of throttling capability and precision as globe valves.
