D341W, D341H PM0.5~PN6 worm drive ventilation butterfly valve

Purpose of valve:
D341H, D341W PN0.5~PN6 ventilation butterfly valve in metallurgy, chemical industry, building materials, power plant, glass and other industries in the ventilation, environmental protection engineering dust-containing cold air or hot air gas pipeline, as a gas medium to regulate the flow or cut off device.
Valve features:
1. The ventilation butterfly valve is designed and manufactured in a new form of structure, which is welded between the centerline plate and short structural plate. It is compact, light in weight, easy to install, small in flow resistance, large in flow, avoid the influence of high temperature expansion, and easy to operate.
2, ventilation butterfly valve without connecting rod, bolt, reliable work, long service life. Can be multi - station installation, not affected by the flow of media
Performance parameters:
Nominal pressure: 0.1mpa
Applicable temperature: ≤425 ℃
Applicable medium: air, flue gas
Leakage rate: ≤ 1%
Valve body material: carbon steel, alloy steel
The electric ventilating butterfly valve is one or two stages and can be operated manually, which can realize the requirements of field operation and remote centralized control
Scope of use: the product can be used in metallurgy, chemical industry, urban construction, electric power and other industries ventilation dust pipe throttling and closure.
Products conform to the standard: JB/T 8692. No Information
