DN5000 butterfly valve

The following is a comprehensive information compilation about DN5000 and DN4000 large-diameter butterfly valves, combined with their technical parameters, application scenarios, and market supply situation:
1、 DN5000 butterfly valve
Technical parameters
Nominal diameter: DN5000 (approximately 5 meters in diameter), suitable for ultra large diameter pipeline systems.
Pressure rating: usually PN0.6MPa (low pressure condition), special design can support higher pressure.
Applicable temperature: -60 ℃~+1100 ℃ (customized heat-resistant alloy material is required for ultra-high temperature type).
Drive mode: electric (such as DKJ-710 actuator) or pneumatic, supporting 4-20mA signal adjustment.
Application scenarios
Control of high flow media such as blast furnace gas and flue gas in the metallurgical and power industries.
Ventilation and dust removal systems in the fields of chemical and building materials (requiring the use of refractory lining).
Market supply
Customized production is required, with a long delivery cycle and prices typically exceeding ¥ 50000.
2、 DN4000 butterfly valve
Technical parameters
Nominal diameter: DN4000 (approximately 4 meters in diameter), commonly used in ventilation and dust removal systems.
Pressure rating: PN0.1~0.6MPa, leakage rate ≤ 1.5% (low leakage type).
Applicable temperature: ≤ 300 ℃ (ordinary type), stainless steel or alloy material should be selected for high temperature.
Drive mode: Supports manual, electric (380V three-phase electricity), or pneumatic (0.4-0.6MPa gas source).
Application scenarios
Flow regulation of dusty gases in the building materials and mining industries (such as flue gas from cement plant kilns).
The desulfurization and denitrification system in the power industry (requiring anti-corrosion lining).
