D41W ventilating butterfly valve/D341W worm wheel ventilating butterfly valve/D641W pneumatic ventilating butterfly valve/D941W electric ventilating butterfly valve is processed into sealing ring with the same material as valve body. Its applicable temperature depends on valve body material selection. The nominal pressure is less than 0.6MPa. It is generally applicable to industrial, metallurgical, environmental protection and other pipelines for ventilation and medium flow regulation.
Main characteristics of ventilated butterfly valve
1, the design is novel, reasonable, unique in structure, light in weight, quick in opening and closing.
2, the operation torque is small, easy to operate, labor-saving and dexterous.
3, adopt suitable materials to meet low, medium and high temperature and corrosive medium.
