Product Details

Product Structure Features

Butt-welded bi-directional sealing butterfly valve has one more offset feature compared to double offset design, which is the seat cone axis offset from the stem centerline that reduces the operating torque. Triple offset butterfly valves are widely used in power plant, petrochemical, metallurgy, water supply and drainage system, municipal construction as throttling flow and shutoff equipments.
