APPLIATIONS
|
 It is
suited for the liquid with corrosion or the hguid cohich� ��needs to be
sealed tightly such as running water,seawater,��� ��sewage,ammonia water,natural
gas,oil products and chemical��� ��products ete. |
| It is
mainly used to control the liquid for the municipal works� ��such as oil,chemical
industry,metallurgy,power station,light�� ��industry,food and the pipe
in waterworks etc. |
| |
FEATURES
|
| The eccentric
symmetrical valve plate has cone polishing edge,�� ��which enables 360°cirumference
concentriced with valve. |
| ZWe SERIES LINING BUTTERFLY VALVES |
When the gate is openning the vale plate separate durring openning ��from
the sealing surface at fisrt of offectively avoid the weat ��of valve
seat. |
|
|
| It is
fitted with fluorine rubber elastic ring at the eexternal� ��of valve
seat to seal the valve plate with valve seat at whole� ��circumference,thus
achieving zero an leakage sealing effect. |
