DN1600mm Hydraulic Three-Lever Butterfly Valve for Metallurgical Bf

Mainly suitable for a blast furnace(BF) hot blast stove system
(including a preheating furnace), used as cold blast valve,
gas shut-off valve, combustion air isolating valve, chimney valve,
play an important role in cutting, also can substitute gate valve.
Drive Mode: hydraulic transmission, electric drive.
Due to its own characteristics, the valve is not relatively glided
between sealing pairs in the process of opening and closing,
the sealing pairs are free from wear, therefore, the durability
and reliability of the sealing can be guaranteed.
