⌈DISTINCTIVE FEATURES⌋
•Pressure Balanced type
•Inverted Lubricated
•API 6D Plug Valve
•Tapered or Cone Plug
•Flanged or B.W
•Metal Seated
•Cast Steel Body
•Bi-Directional Seal
⌈ MAIN CHARACTERISTICS ⌋
•Glofa pressure balanced plug valves are designed of lubricated
sealing structure by injecting high pressure sealing oil &
grease from the plug nozzle into the valve, which will generate one
layer of high pressure sealing surroundings, in another words, will
form one oil slick between the body and plug sealing surface, the
oil slick could not only act as sealant member, but also function
as lubricant, easy to open and close. In order to further decrease
the operating torque, the plug valve passageway are designed of
rectangular shape. The sealing surface is welded STL or treated by
hardening process to strengthen its abrasion-proof and
corrosion-resistance ability, extending the service life. The plug
surface is made of mirror structure and grind with the body seal
surface then, the much lower operating torque may be
achieved.
⌈ DESIGN ADVANTAGES ⌋
•Glofa pressure balanced plug valves are inverted type, there is
one check valve on the top, when the valve is shut-off, the
injected oil make the plug effect with one lifting force since of
the area difference of top plug and bottom plug, making the valve
acquiring better sealing performance. At the moment the plug valve
is open, the pressure in the low cavity of the body and the
pipeline pressure get balanced, the plug will effect with one
thrust downward by the high pressure sealing oil in the top cavity,
one small gap will occure between the plug and the body sealing
surface, the torque rotating the plug could be decreased
effectively.
