Fl 4 base eccentricity butterfly valve
Application
This butterfly valve is fit for the medium pipe of smelt metal, electric power, petroleum, chemic industry, city planning project and water factory whose temperature is lower than 180°( to on-off the beamed control.
Characteristic
- The structure is seasonable, on-off is portable and flexible, maintain and use is convenient.
- Valve base adopt Fl 4.
- This butterfly valve adopts double eccentricity structure. When the butterfly board is on the ten to the whole opened, the valve and butterfly board will complete in non-contact state and when it closed, butterfly board will partial move to the valve base with valve stem running which lead to valve base, valve stem and sealing ring hardly frictional, thereby avoid the abrasion and extend the service life.
- Sealing base fission setting which convenient for adjust and maintain.
- Small volume, light weight, simple and reasonable structure, convenience use and setting.
