An angle globe valve is a type of valve that combines the features of an angle valve and a globe valve. It is used to control the flow of a liquid or gas through a pipe and is designed with a 90-degree angle between the inlet and outlet ports, similar to an angle valve. The internal structure of the valve is similar to that of a globe valve, which allows for precise flow control and tight shutoff.
Key features and benefits of angle globe valves:
- Compact installation: The 90-degree angle design allows angle globe valves to be installed in tight spaces or close to walls, making them ideal for applications with limited room for valve installation.
- Precise flow control: Angle globe valves offer excellent flow regulation capabilities, allowing for accurate control of the flow rate. The valve disk can be positioned to restrict the flow as needed, providing stable and precise flow control.
- Tight shutoff: When fully closed, angle globe valves provide a tight seal, preventing leakage and ensuring reliable shutoff.
- Reduced piping complexity: By combining the flow redirection and control capabilities in a single valve, angle globe valves can simplify piping layout and reduce the number of fittings required.
- Replaceable components: Many angle globe valves feature replaceable valve seats and disks, allowing for easy maintenance and repair without replacing the entire valve body.
However, angle globe valves also have some limitations:
- Higher pressure drop: Due to the more complex flow path through the valve body, angle globe valves tend to have a higher pressure drop compared to other valve types like ball valves or gate valves.
- Slower operation: Angle globe valves require multiple turns of the handwheel or actuator to fully open or close the valve, making them slower to operate compared to quarter-turn valves.
Angle globe valves are used in various applications, including:
- Steam systems
- Boiler feedwater systems
- Condensate return lines
- Heat exchanger control
- Bypass lines
- Instrumentation and sampling lines
Their compact design, precise flow control, and tight shutoff capabilities make them a reliable choice for many industrial and commercial applications where space is limited, and accurate flow regulation is required.
