Name:D941W electric ventilation butterfly

Product description :

The D941W electric ventilation butterfly
Uses and Features
This butterfly valve with the valve body the same material processed into the ring, using electric or pneumatic drive. Its application temperature of the body selection, nominal pressure ≤ 0.6MPa, are generally applicable to the industry, metallurgy, environmental protection and other pipe for ventilation to regulate the use of media flows. The main features are as follows:
1, the novel design, reasonable, unique structure, light weight, open and close quickly.
2, the operating torque is small, easy to operate, saving smart.
3, used to adapt materials to meet the low, medium, high medium temperature and corrosive media.
