Product Detail

1. Double Eccentric High Performance Flange Type Butterfly Valve comes with integral flanges and double eccentric sealing structure.

2. Disc separates from seat quickly at the instant of opening, reducing sealing surface friction and wear and extending service life.

3. Metal to metal or metal soft combined sealing optional, covering wider temperature and pressure range.

4. Suitable for water, steam and compressed air media, available for single end installation removal and maintenance.

1. Double eccentric design reduces sealing surface friction, longer service life than concentric butterfly valve.

2. Integral flanges, installation removal and maintenance do not depend on pipes on both sides.

3. Sealing type can be switched between metal seal and composite soft seal according to working conditions.

4. Higher temperature and pressure capability than ordinary concentric butterfly valve.

5. Moderate operating torque compatible with various automated actuators.

6. Suitable for process media such as water, steam and compressed air, for frequent on off and modulating service.
