High Quality Industrial Y-Pattern Glove Valve China factory supplier Manufacturer
What is Y-Pattern Glove Valve ?
Y-Pattern Glove Valve ,is normally designed and manufactured according to Germany standard and European standard EN13709.as normal,it's linear motion closing-down valve used to start, stop or regulate the flow using a closure member referred as a disc. the Y-Pattern Glove Valve 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.
Bellows have a limited service life, which means the possibility of a rupture is likely. This is why a conventional packing assembly is always included in a bellows-equipped bonnet.So the bellows seal is an extra packing sealing for the gate valves,it's suitable for some severe working conditions.
normally there are three primary body patterns or designs for Y-Pattern Glove Valve:
- 1).Standard Pattern (also as Tee Pattern or T – Pattern or Z – Pattern)
- 3).Oblique Pattern (also known as Wye Pattern or Y – Pattern)
Main features of Y-Pattern Glove Valve
In particular chemical processes the fluids in the pipes are often toxic, radioactive and hazardous. Bellows seal globe valves are used to prevent leakage of any toxic chemical to the atmosphere. Body material can be selected from all available materials,The bellow can be supplied in different materials like 316Ti, 321, C276 or Alloy 625.
- 1).There is wide range of capabilities as available in standard pattern(streght pattern),Angle pattern,and Wye pattern(Y pattern).
- 2).Metal bellows seals the moving stem and increases durability of packed stem seal valves.
- 3).Bellow-sealed valves are usually leak tested using a mass spectrometer to detect leakage rates below 1x10E-06 std.cc/sec.Double sealing design (bellows seal and stem packing) if the bellows fail, valve stem packing will also avoid leakage,and in conformity with international tightness standards;
- 4).Easy Machining and resurfacing of the seats,for various purposes.
- 5)..Short travel distance of the disc(stroke) between the open and closed positions,Bellows seal globe valves are ideal if the valve has to be opened and closed frequently;
