Double Eccentric Butterfly Valves
BVD01 are characterized by unparalleled performance and quality in the range of high performance double offset butterfly valves.
Optimized lip-type seat can automatically compensate for temperature and pressure variations. It has a self-regulating capacity and its sealing performance is safe and reliable.
Users can replace the seat just by taking down the segment on site without dismantling the valve, plate and shaft, leading to reduced maintenance costs and extended service life.
