What is an Angle Globe Valve?
The body configuration of an angle pattern globe valve is based on the standard globe valve design. It features plug-shaped valve discs for opening and closing, with a sealing surface that can be flat or conical. The disc moves linearly along the fluid’s centerline, and the valve ends are positioned at a 90-degree angle, allowing the fluid to make a single 90-degree turn.
Angle globe valves have a significantly smaller flow coefficient compared to oblique-style globe valves. They are particularly suitable for applications involving pulsating flow, as they can withstand the slugging effect of such flow patterns.
There are two types of stem movement modes for globe valves. The first is the raising stem type, where the stem is raised and lowered independently of the handwheel, which remains stationary.
The second type is the lifting rotary stem type, where both the handwheel and the stem rotate and lift together. In this design, the nut is positioned on the valve body.
Classification of Angle Globe Valve
Angle globe valves can be categorized based on several parameters:
- Design of Valve Disc: Includes conventional or ball disc, composition disc, and plug type disc.
- Disc-Stem Configurations: Comprises rotating stem with integral or non-integral disc and non-rotating stem with integral or non-integral disc.
- Valve Stem Screw: Available as inside stem screw or outside stem screw.
- Bonnet Design: Includes bolted bonnet, welded bonnet, flanged bonnet, union ring bonnet, and pressure seal bonnet.
How does an Angle Globe Valve Work?
The angle globe valve features plug-shaped valve discs for opening and closing. The sealing surface can be smooth or conical, and the disc moves linearly along the fluid’s centerline. In an angle globe valve, the inlet and outlet channels are positioned at a 90° right angle to each other. This design causes the medium to change its flow path, leading to a pressure drop.
Features and Benefits of Angle Globe Valve
The angle globe valve is designed with simplicity and efficiency in mind. Its sealing surface, made from rough steel, is resistant to wear, corrosion, and leaks, contributing to a long service life. The valve stem undergoes nitriding and tempering, improving its resistance to corrosion and friction, while maintaining reliable sealing.
A significant advantage of the angle globe valve is its ability to be installed at a 90° angle within the piping structure. This design removes the need for 90° elbows, making both installation and operation more straightforward. The valve is particularly suitable for synthetic ammonia processing systems and fertilizer plant refrigeration systems.
For high-pressure applications, such as ammonia synthesis, the 2500LB angle globe valve is frequently used. Constructed from forged steel, it meets stringent sealing requirements and manages strong fluid forces on the disc. Additionally, it requires minimal driving force during operation.
Angle Globe Valve Application
Angle globe valves are suitable for various industries, including gasoline, minerals, pharmaceuticals, fertilizers, electric power, recycling machinery, gas supply, cooling and freezing systems, boiler steam systems, and hot oil systems.
These valves can be used to either shut off or connect the pipeline medium under different conditions, with nominal pressures ranging from 150 LB to 2500 LB and working temperatures from -40°C to 500°C.
Design and Sizing Considerations
- Angle globe valves are suitable for pipelines where strict fluid resistance requirements, such as pressure loss, are not a concern.
- They typically come in practical sizes up to NPS 12 (DN 300), with valves larger than NPS 12 (DN 300) being rare. However, sizes up to NPS 48 (DN 1200) have been manufactured and used.
- The pressure difference across the valve disc should not exceed 20 percent of the maximum upstream pressure or 200 psi (1380 kPa), whichever is lower.
Application and Installation
- Angle globe valves can be used in equipment or pipelines with high-temperature and high-pressure flow mediums, including steam pipelines with DN<200mm.
- For low-temperature and low-pressure applications, valves are installed with pressure below the disk.
- For high-temperature and high-pressure applications, such as steam, valves are installed with pressure above the disk.
- These valves are suitable for small applications, including instruments, sampling, and pressure gauges.
- For highly toxic mediums, valves with bellows seals are recommended.
Industry Applications
- Angle globe valves are commonly found in industries such as shipbuilding, petrochemicals, pharmaceuticals, and aerospace.
- They are used to control medium flow in systems like cooling water and fuel oil.
- These valves are also appropriate for services involving feedwater, chemicals, air, lube oil, and similar applications where pressure drop is not a concern.
- They are especially valuable where leakage and safety are critical, such as high point vents and low point drains.
- Their ability to manage a wide range of flow and pressure drops makes them ideal for control circuits. Their durability to handle extensive temperatures and pressures enables use in high-pressure environments like steam and hydraulics.
How to select an Angle Globe Valve?
When selecting an angle globe valve, consider the following essential criteria:
- Purpose and Operation: Choose the valve based on its intended purpose, operating conditions, and control methods.
- Medium Properties: Select the valve according to the properties of the working medium, including working pressure, temperature, corrosion resistance, viscosity, presence of solid particles, and whether the medium is toxic, flammable, or explosive.
- Fluid Characteristics: Consider the valve’s suitability for the fluid characteristics, such as flow resistance, discharge capacity, flow behavior, and sealing level.
- Installation and Size: Choose the valve based on installation requirements, including nominal diameter, connection methods and sizes, external dimensions, and weight limitations.
- Additional Requirements: Take into account additional factors like valve reliability, service life, and the explosion-proof performance of any associated electric devices.
Some Important Points in Selection Parameters
When selecting valves for control purposes, consider the following additional parameters:
- Methods of operation
- Maximum and minimum flow rates
- Pressure drops during regular flow and at closing
- Maximum and minimum inlet pressures
In addition to these basics, examine the internal structures of various valves in detail to make a well-informed choice. Valves control the medium flow in pipelines by opening and closing. The shape of the valve flow channels affects its flow characteristics, which should be considered when selecting the most suitable valves for the pipeline system.
