High Quality Industrial Globe check valve China factory supplier Manufacturer
What's the Globe check valve ?
Globe check valve is designed and manufactured according to former Germany standard,DIN and nowadays European standard EN13709.it's mainly used in the countries in European Union.
it's linear motion closing-down valve used to start, stop or regulate the flow using a closure member referred as a disc. The seat opening changes proportionately with the travel of the disc which is ideal for duties involving flow regulation. the DIN-EN 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.
the Globe check 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.
normally there are three primary body patterns or designs for Globe check valve:
- 1).Standard Pattern (also as Tee Pattern or T – Pattern or Z – Pattern)
- 2).Angle Pattern
- 3).Oblique Pattern (also known as Wye Pattern or Y – Pattern)
Main features of the Globe check valve
Standard pattern(straight pattern)
Angle pattern
Standard pattern with bellows seal
- 1).Short travel distance of the disc(stroke) between the open and closed positions, Globe check valve are ideal if the valve has to be opened and closed frequently;
- 2).Good sealing capabilities
- 3).There is wide range of capabilities as available in standard pattern(streght pattern),Angle pattern,and Wye pattern(Y pattern).
- 4).The DIN-EN globe valve can be used as a SDNR valve,globe-check valve by modifying the design slightly.
- 5).Easy Machining and resurfacing of the seats,for various purposes.
- 6).Moderate to good throttling capability,by modifying the structure of seat and disc.
