What Is an Angle Type Globe Valve?
An angle-type globe valve is a modification of traditional globe valves featuring right-angled intake and exit ports to enable reduced pressure drop when installed at pipe changes.
An angle-type globe valve is a modification to a Z-body globe valve in which its diaphragm (the basic glove) can move at right angles to its pipe axis, offering more efficient use by only needing one elbow instead of two.
The valve has a globe-shaped body with a movable disk or plugs that can be raised or lowered to control the flow of fluid through the valve. The angle between the inlet and outlet ports creates a change in the direction of the fluid flow, which can help to reduce pressure drop and minimize turbulence.
Types of Angle Type Globe Valve
Globe valves are mechanical control valves used to regulate flow and pressure. Available in various styles and forms, globe valves have many potential applications in regulating both.
Angle globe valves feature an innovative design that enables smaller pressure drops than standard pattern globe valves and requires fewer fittings for installation.
- Y-Pattern
Y-Pattern angle type globe valves are variations on standard Z-body globe valves with their seats and stem angled at approximately 45 degrees, creating a straighter fluid path and decreasing pressure loss.
A Y-pattern globe valve seat may be composed of either soft or metallic material depending on its application and temperature range; soft-seated seats typically serve low-temperature systems up to 60deg C, while metallic seats are utilized at higher temperatures beyond this threshold.
- Straight-Through
Straight-Through angle type globe valves can switch the flow direction by 90 degrees without using an elbow or an extra pipe weld, as well as offering lower pressure drops than standard globe valves. They’re especially well suited for applications involving intermittent flow because of their ability to control their pulsing effects without becoming stuck open or closing over time.
Angle valves should typically be installed so that their outlet pipe points downward, thus reducing the likelihood of fluid clogging or corrosion over time.
- Right-Angle
Right-Angle angle globe valves are versatile devices used in numerous industries, including shipbuilding, petrochemicals, and pharmaceuticals, to regulate flow and pressure in pipelines.
This type of valve features a spherical body with two ports connected by a passageway, enabling fluids to freely pass between both ports when opened.
- Direct-Flow
Direct-Flow angle-type globe valves feature linear motion disks for controlling fluid flow. Their seat opening varies proportionally with disc travel, making this an excellent solution for tasks requiring flow management.
These linear motion globe valves are an excellent solution for steam and condensate service, temperature or pressure regulation in pipelines, and nuclear plant process control and offer high degrees of shutoff capability.
Applications of angle-type globe valve
Angle-type globe valves are widely used in various industries where there is a need for precise flow control of liquids or gases. Here are some of the applications of angle-type globe valves:
- Chemical Processing
- Food and Beverage
- HVAC
- Oil and Gas
- Pharmaceutical
- Power Generation
- Water Treatment
