Introduction to pneumatic ventilation butterfly valve d641w-1c The pneumatic ventilation butterfly valve is processed into a sealing ring with the same material as the valve body and is electrically or pneumatically driven
Its applicable temperature depends on the material selection of valve body, nominal pressure ≤ 0
6MPa, generally applicable to industrial, metallurgical, environmental protection and other pipelines for ventilation and medium flow regulation
Its main features are:
1
Novel and reasonable design, unique structure, light weight, quick opening and closing
2
Small operating torque, convenient operation, labor-saving and dexterous
3
Suitable materials shall be used to meet the requirements of low, medium and high medium temperatures and corrosive media
Manual mechanism: hvsd manual mechanism
