Gate valves and globe valves belong to the category of linear motion valves which are fluid flow control valves. Gate valves are linear motion valves that feature a sliding gate-like disc. This disc moves up and down within the valve body to either open or close the flow passage. When fully lifted, gate valves allow unobstructed flow, and lowering the gate creates a tight seal to stop the flow. They are designed for full flow capacity and low-pressure drop, making them suitable for applications where minimal restriction is required. Industries such as oil and gas, water treatment, and power generation commonly use gate valves.
Whereas globe valves, also known as stop valves, have a movable plug-like disc and a stationary ring seat. The disc moves perpendicular to the flow direction, providing precise control over the flow rate. By adjusting the position of the disc, the flow can be increased, decreased, or shut off. Globe valves are versatile and can handle a wide range of pressures and temperatures. They find applications in HVAC systems, steam pipelines, and industrial processes that require moderate control accuracy.
While gate valves excel in shutoff capability, globe valves are known for their flow control and regulating functions. The choice between these valves depends on specific system requirements, including the desired flow rate, pressure, and control accuracy.
