What's Flanged Glove Valve ?
Globe valves are linear motion closing-down valves used to start, stop or regulate the flow using a closure member referred as a disc. The seat of a globe valve is in the middle of and parallel to the pipe, and the opening in the seat is closed off with a disc or plug.The globe valve disc can completely close the flow path or can be removed entirely. The seat opening changes proportionately with the travel of the disc which is ideal for duties involving flow regulation. Globe valves are most suitable and widely used to control or stop the flow of liquid or gas through a pipe for throttling and controlling fluid flow and are generally employed in small size piping.
ASME Globe valve Flanged Glove Valve is one of the most popular design of globe valves,for US and API system.the inside diameter,materials,the face to face,wall thickness,pressure temperature,are are defined by ASME B16.34.
In addition,depending on the design of the seat and disc, the seating load of Flanged Glove Valve can be positively controlled by a screwed stem. The sealing capacity of the Flanged Glove Valve is very high. They can be used for on-off duty.Because of the short travel distance of the disc between the open and closed positions, Flanged Glove Valve are ideal if the valve has to be opened and closed frequently. Thus, globe valves can be used for a wide range of duties.
the Flanged Glove Valve can be used for throttling purposes as well.Many single-seated valve bodies use cage or retainer-style construction to retain the seat-ring, provide valve plug guiding, and provide a means for establishing particular valve flow characteristics. it can also be easily modified by change of trim parts to change the flow characteristic or provide reduced-capacity flow, noise attenuation, or reduction or elimination of cavitation.
ASME Globe Valve Body Patterns,there are three primary body patterns or designs for Globe valves, namely:
- 1).Standard Pattern (also known as Tee Pattern or T – Pattern or Z – Pattern)
- 2).Angle Pattern
- 3).Oblique Pattern (also known as Wye Pattern or Y – Pattern)
Main feature of Flanged Glove Valve
- 1).Good sealing capabilities
- 2).Short travel distance of the disc(stroke) between the open and closed positions,ASME globe valves are ideal if the valve has to be opened and closed frequently;
- 6).Moderate to good throttling capability,by modifying the structure of seat and disc.
- 7).Bellows seal is available on request.

Application of Flanged Glove Valve
Flanged Glove Valve ASME Globe Valve is widely used in a wide range of services; both low pressure and high pressure fluid services. The typical applications of globe valves are:
- 1).Designed for frequent on-off pipeline,or throttling the liquid and gaseous medium
- 2).Fluids:Water, steam, air, crude petroleum and petroleum products, natural gas, gas condensate, technological solutions, oxygen, liquid and non-aggressive gases
- 3).Cooling water systems requiring flow regulation.
- 4).Fuel oil system requiring leak-tightness.
- 8).Boiler vents and drains, Steam services, main steam vents and drains, and heater drains.
- 9).Turbine seals and drains.
