Operation method Handle, worm, motor-drive unit, pneumatic drive unit
Application fields Used as control and cut-off equipment for smelting, chemical engineering, sewage engineering, environmental protection system and control subsystems of water plant, power plan and steel plant.
Other remarks1 Compact structure, easy installation and disassembly, repair friendly and light weight
Other remarks2 It has a certain adjustment capability, and can be used as a control valve.
Other remarks3 With the triple-eccentric structural design, the sealing face is separated as soon as opening, so the mechanical wearing and friction between two sealing faces is eliminated during the opening and closing of butterfly plate, the operation torque is lowered, and the service life is longer.
Other remarks4 Good sealing performance of zero leakage.
Other remarks5 Wide range of application - triple-eccentric metallic sealing butterfly valves have a wide range of temperature, pressure and diameter.
