Globe style control valves
Globe style control valves, commonly known as globe valves, are the most common type of control valve. They got their name because in the early design of the valve the interior cavity of the valve had a circular or globe shape. Globe valves are also known as Linear Valves because the stem that actuates the valve moves up and down in a straight line.
Globe valves are recognized for their versatility and ability to provide accurate throttling control.
Ramén Valves offers a wide range of globe style control valves from Badger Meter. Feel free to contact us if you would like more information about our globe style control valves.
How does a globe style control valve operates?
Globe style control valves differ significantly from rotary valves such as ball, eccentric plug and butterfly valves in that they have a “torturous” flow path. The flow changes direction several times as it passes through the valve regardless of the stem travel. This torturous path acts to dissipate energy due to friction which in turn makes the globe valve less susceptible to noise and cavitation problems. Another benefit to the globe style control valve design is that it can control extremely low Cv’s/Kv’s.
Advantages of the globe style control valve
Precise Control: Globe style control valves provide accurate and repeatable flow control across a wide range of flow rates.
Leakage Prevention: When fully closed, globe style control valves provide a tight shutoff, minimizing leakage.
Steady Flow: The linear flow path of globe style control valves helps maintain steady flow characteristics, reducing turbulence and pressure drop.
Globe style control valves are a common type of valve used in various industries and particularly in the process industry. They are mainly used to control more demanding applications and processes where high accuracy is required. There are also trims that address issues such as cavitation and high noise.
Globe style control valves are available with specialized trim that allows them to handle very high pressure drops of both liquids and gases. There is also a great variety of flow characteristics which allow them to be used in many different applications. They come in sizes ranging from ¼” up to 20” with sizes ½” through 8.0” being the most common.
