What type of valve is typically used for regulating water flow in heating systems?

The globe valve is commonly used for regulating water flow in heating systems due to its design, which allows for precise control over flow rates. The globe valve consists of a spherical body with an internal baffle that separates two chambers. This structure enables the fluid to flow through the valve in a direction perpendicular to the seat, allowing for effective throttling.

This throttling capability is critical in heating systems, where maintaining specific temperatures and flow rates is essential for efficient operation. Globe valves can be adjusted to provide a wide range of flow control, which is particularly beneficial in applications where temperature regulation is required.

In contrast, while butterfly valves offer quick shut-off and are useful for larger pipes, they do not provide the same level of control and precision as globe valves. Gate valves, on the other hand, are designed primarily for fully open or fully closed positions and are not intended for flow regulation. Lastly, check valves are designed to prevent backflow and do not regulate flow direction or volume. Therefore, in heating applications where flow regulation is necessary, globe valves are the preferred choice.
