Globe Valves

A globe valve, a cylindrical instrument designed to halt and regulate fluid flow in pipelines, earns its name from its shape. It comprises two body halves separated by an internal baffle. While globe valves may incur greater pressure drops compared to gate valves, they remain viable where pressure drop is not a critical factor. Additionally, when employed for throttling, globe valves are also known as throttle valves.

These valves are instrumental in shutting off and controlling the flow of liquids and gases in pipes. The stem rotates to press the valve disc against the seat, effectively stopping the flow. Many conventional globe valves feature a yoke that doubles as a cooling rib, ensuring the handwheel remains at a low temperature.

ACEV globe valves offer a reliable seal with minimal leakage risks, making them a preferred choice for high-pressure industrial piping systems. Their primary function is to start, stop, and regulate the flow of liquids and gases in pipes. Featuring a movable disk component and a stationary ring seat within a cylindrical body, the globe valve's seat, centrally located alongside the pipe, utilizes a disk or plug to shut off the seat's opening. This design allows globe valves to handle flow in both directions seamlessly.

Globe valves are ingeniously designed to direct the flowing media on a gentle vertical detour through the valve cavity, rather than impeding it with a perpendicular blockage. As the valve stem is rotated via a wheel, it raises to permit media passage, with the disc moving parallel to the flow. The stem's position serves as a clear indicator of the valve's open or closed status.

This vertical movement mechanism allows globe valves to not only start and stop media flow but also regulate it. The flow rate is determined by the distance between the disc and the seat: a wider gap permits a higher media volume. Globe valves excel at throttling, enabling smooth flow regulation in a partially open position, which helps mitigate water hammer.

Based on body shape, globe valves are primarily categorized into three types: the straight or "T" type, the angle or "90-degree" type, and the Y-pattern or "wye globe valve".
