High performance butterfly valve

High-performance butterfly valve adopts the latest three-eccentric design principle, which has the characteristics of good sealing, normal body flow path, large flow capacity, less friction between butterfly plate and valve seat, long service life, wide application temperature range, convenient maintenance and so on.

Model BU/HP series can be widely used in automation and remote control of petrochemical, power, food, light industry and other industries.

Structural characteristics

_Soft seals adopt double eccentric structure, small wear and tear between butterfly plate and valve seat, low leakage.

Long life;

_Hard seals adopt the latest three-eccentric structure, with small closing force, tight sealing and long life.

Long life, wide temperature range, etc.
