Globe VALVE

Design: Globe valves consist of a spherical body, a movable disc or plug, a stem, and a handwheel or actuator. The disc or plug is connected to the stem, which is threaded into the bonnet or the top of the valve body. The stem moves the disc or plug up and down to control the flow of fluid through the valve.

Control and regulation: Globe valves are primarily used for regulating and controlling the flow of fluids, rather than completely shutting off the flow. They are designed for precise flow control and can be used in applications where a precise and accurate flow rate is required.

Linear flow: The flow of fluid through a globe valve is linear, meaning that the fluid flows in a straight line through the valve. This linear flow pattern minimizes turbulence, which can cause wear and tear on the valve and the piping system.

Pressure drop: Globe valves are known to cause a significant pressure drop across the valve when they are partially open, which can affect the overall efficiency of the system.

Different materials: Globe valves can be made from a variety of materials, including cast iron, carbon steel, stainless steel, bronze, and exotic alloys. The choice of material depends on the specific requirements of the application, such as the type of fluid, temperature, and pressure.

Manual or automated operation: Globe valves can be operated manually using a handwheel or lever, or they can be automated using actuators, such as electric, pneumatic, or hydraulic actuators. Automated globe valves enable remote control and integration into control systems.

Different types: There are different types of globe valves, including angle globe valves (which have an angled body to reduce pressure drop), Y-pattern globe valves (which have a Y-shaped body to reduce pressure drop), and needle valves (which have a slender, tapered disc for fine flow control).
