Features
Globe valves use a linear motion to open and close. The valve's disc or plug moves up and down on the valve stem, which controls the flow of fluid through the valve.
Globe valves are excellent for throttling and controlling flow. The design allows for precise flow regulation, making them ideal for applications where accurate flow control is necessary.
The flow path in a globe valve is typically S-shaped, with the fluid entering the valve body, passing through the valve seat, and exiting on the opposite side. This design creates a pressure drop, which helps in flow regulation.
Globe valves come in various body designs, including T-pattern (most common, changes direction), Y-pattern (straighter path, reduced drop), and angle pattern (changes flow by 90 degrees).
The disc (or plug) can be designed in different shapes, such as flat, parabolic, or needle-like, depending on the desired flow characteristics. The seat can be either integral with the body or renewable.
Globe valves provide good sealing capabilities. They are effective in providing a bubble-tight shut-off when fully closed, depending on the design and material.
Globe valves can be operated manually using a handwheel or can be automated with electric, pneumatic, or hydraulic actuators, allowing integration into various control systems.
Designed to withstand high pressures and temperatures, making them suitable for steam systems, high-temperature fluids, and other demanding applications.
Made from a variety of materials, including cast iron, carbon steel, stainless steel, brass, bronze, and various alloys, to suit different fluids, including corrosive or abrasive media.
Commonly used in applications where flow control, throttling, or frequent operation is required, such as HVAC systems, water treatment, chemical processing, and power generation.
One of the downsides of globe valves is their relatively high pressure drop compared to other valve types, such as gate or ball valves, due to the tortuous S-path the fluid takes.
Globe valves are relatively easy to maintain and repair. The seat and disc can be accessed and replaced without removing the valve body from the pipeline.
Application
Ideal for applications requiring precise flow control and throttling. They can be adjusted to various open positions to regulate fluid flow rates.
Commonly used in steam applications due to their ability to handle high temperatures and pressures in heating systems, steam turbines, and networks.
Used to regulate the flow of treated water and chemicals in plants, and to control water pressure and flow in municipal distribution systems.
Controls the flow of hot water, chilled water, and steam to maintain desired temperatures and flow rates in HVAC circuits.
Used for controlling the flow of crude oil, refined products, and natural gas in high-pressure applications with a wide range of fluids.
Controls the flow of various chemicals, including corrosive and hazardous substances, under varying temperatures and pressures.
Critical for precise flow control of water, steam, and fuel in boiler feedwater systems, cooling systems, and fuel supply lines.
Used to control process water, steam, and cleaning agents under strict sanitary standards with highly precise flow regulation.
Controls the flow of water, fuel, and other fluids in both seawater and freshwater systems on ships and offshore platforms.
Specifically deployed in systems with extreme pressures and temperatures, such as industrial boilers, heat exchangers, and autoclaves.
Controls gas flow in low-pressure vacuum applications, providing highly reliable sealing capabilities.
Designed to handle extreme thermal stresses and control liquid nitrogen, liquid oxygen, and other low-temperature fluids.
Provides precise regulation of fuel flow across pipelines, oil refineries, and fuel distribution networks.
Used to safely control the release of gases or liquids from pressurized vessels and pipelines.
