Globe Valve
Efficient Flow Control Solutions
A Globe valve operates through linear motion and is primarily engineered for flow control, starting, and stopping flow. Its design allows the valve's disk to be adjusted to modify or completely shut off the flow path. For premium quality globe valves in Hubli, Neo Valves is your go-to choice. Count on Neo Valves for precision-crafted globe valves that guarantee optimal flow control and performance in diverse applications.
Globe valves are extensively used for controlling flow, offering a wide range of flow control capabilities. Although they may incur slightly higher pressure drops than straight-through valves like gate, plug, or ball valves, they are suitable where pressure drop isn't the primary concern. However, due to the system pressure being transferred to the valve stem, the practical size limit for these valves is typically NPS 12 (DN 300), although exceptions with larger sizes exist. Globe valves above NPS 12 (DN 300) require immense force to operate under pressure.
How Globe Valve Works
Globe valves function through linear motion, allowing for the adjustment of the valve's disk to regulate or completely shut off the flow path as required.

Frequently Asked Questions
What distinguishes globe valves from other valve types in terms of operation?
Globe valves operate through linear motion, offering precise control over flow by adjusting the valve's disk.
What applications are most suitable for globe valves considering their design for flow control?
Globe valves are well-suited for various applications where precise flow control, starting, or stopping of flow is necessary. They are commonly employed in industries such as oil and gas, power generation, and water treatment.
How do globe valves handle high-differential pressure-throttling service, and what considerations are essential for their effective operation in such conditions?
Globe valves employed in high-differential pressure-throttling service require specially designed valve trim. Due to the system pressure exerted on the valve stem, considerations for valve design and trim become crucial to prevent premature failure and ensure satisfactory service in these conditions.
