Product Introduction:
Ventilation butterfly valves (duct butterfly valves, flue gas butterfly valves) are center-line welded butterfly valves, specifically designed for low-pressure, high-flow gas pipelines.
They achieve duct opening/closing, airflow regulation, and pressure balancing through 0°~90° rotation of the butterfly plate.
They are mainly used in gas pipelines carrying dust-laden cold air, hot air, flue gas, exhaust gas, and air.
And are core control equipment in dust removal systems, industrial kilns, environmental protection waste gas systems, HVAC systems, and metallurgical mining pipelines.
Main Features
Low flow resistance, minimum pressure loss, reduce fan energy consumption.
Compact welded structure, light weight, easy installation and maintenance.
Resist dust accumulation and high temperature, stable operation for flue gas service.
Small operating torque, quick 90° open/close, suitable for frequent throttling.
Multiple options of material, actuator and connection type, available in large size up to DN6000.
Technical Data:
Size: DN100 ~ DN6000.
Nominal Pressure: PN0.1 / PN0.25 / PN0.6 MPa.
Connection: Flanged / Wafer / Butt-welded.
Operation: Manual worm gear, Pneumatic, Electric (on-off / modulating, explosion-proof optional).
Body Material: Q235 Carbon Steel, WCB, SS304, SS316L, SS310S.
Temperature Range: -40℃ ~ 1000℃ (depends on material selection).
Seal Type: Metal hard seal / Soft seal / Non-sealing type.
Application:
Dust collection & waste gas treatment, cement plant kilns, metallurgical flue ducts, power plant desulfurization & denitrification, HVAC ventilation, chemical exhaust gas pipelines.
All valves are equipped with professional export protective packaging.
With protective caps on the sealing surfaces, rust-proof treatment, and shock-absorbing material filling to ensure intact transport; the loading is secure and safe.
We can also customize packaging according to customer requirements.
Regarding transportation methods, we can provide appropriate transportation options based on the cargo requirements and the customer's timeliness requirements.
Common transportation methods include: sea freight, air freight, land freight, and express delivery.
