Exd II Bt4 Flange Explosion-Proof Flanged Electric Ball Valve/
Floating Ball Valve
The control mode can be switch on-off type or regulation type. Its
usually used in the occasions with strict sealing requirements in
addition to controlling gas liquid and steam medium it is also
suitable for controlling sewage and medium containing fibrous
impurities widely used in petroleum chemical industry metallurgy
light industry paper making power station refrigeration and other
work fields.
| No leakage of two sides self-seal ball structure. |  | Special designed PTFE seal materialless the friction of the trim
movement. |
| Excellent cuting ability of O type valve trim | Optional O type or Vtype valve trim
