D341H D341W ventilation butterfly valve

Valve purpose:

D341H and D341W type PN0.5 ~ PN1 ventilation butterfly valves are used as gas medium to regulate flow or cut off devices in the dust containing cold air or hot air gas pipeline of ventilation and environmental protection engineering in metallurgy, chemical industry, building materials, power station, glass and other industries.


Valve features:

1. The ventilation butterfly valve is designed and manufactured with the new structure of welding the central line type disc plate and the short structural steel plate. It has the advantages of compact structure, light weight, easy installation, small flow resistance, large flow volume, avoiding the influence of high temperature expansion, and easy operation.
2. There is no connecting rod and bolt in the ventilation butterfly valve, so it works reliably and has long service life. It can be installed in multiple positions, and is not affected by the flow direction of media.

Performance parameters:

Flange connection standard: GB / t9115
Nominal pressure: 0.1MPa
Applicable temperature: ≤ 300 ℃
Applicable medium: air and smoke
Leakage rate: ≤ 1%

Valve body material: carbon steel, alloy steel

The electric device of ventilation butterfly valve is driven by one or two stages, and can be operated manually, which can meet the requirements of field operation and remote centralized control.
