ZKJWdy/ZDTWdy/SWdy-1The circular electric (manual) multi leaf ventilation butterfly valve is a new product jointly developed by our company and scientific research institutions, and has passed relevant identification. It is a reliable equipment for regulating and opening and closing air, flue gas, dust gas and combustible gas, The valve can be combined with various actuators to form a valve with different performance. It has many blades, low noise, light weight, small operating torque, large circulation capacity, convenient operation and low price. It is especially suitable for large diameter, large flow and low pressure difference occasions. It is widely used in metallurgy, mining, building materials, chemical industry, power station and other industrial departments.

Nominal pressure: 0.1MPa
Applicable temperature: - 20-300 ℃
Leakage rate: common type ≤ 3%, low leakage rate ≤ 1%
Applicable media: air, flue gas, dust containing gas and combustible gas
Power supply voltage: 220 V or 380 v.ac
