Manual ventilation butterfly valve

The ventilation butterfly valve is made into a sealing ring with the same material as the valve body, and the applicable temperature is determined by thematerial selection of the valve body, and the nominal pressure is 0.6mpa, which is generally applicable to the ventilation of the pipeline such asindustry, metallurgy, environmental protection and the like to regulate the flowof the medium. The main characteristics of the invention are as follows:

1.The design is novel, reasonable, and unique in structure, light in weight and quick in opening and closing.

2.The operating moment is small, the operation is convenient, and the labor is labor-saving.

3.The applicable materials have been used to meet the temperature of different media and its corrosive medium, etc.

4.The principle of actuator, wiring diagram, technical parameters can be found inthe instructions.

5.This valve can be made according to customer requirements (when not installed horizontally, please indicate the angle in the contract)

6.Please indicate in the contract if the accessory is required.

Theventilation butterfly valve is a valve made of steel plate welding, which has the characteristics of small size, light weight, easy installation and thelike, and because the flow resistance is small, the circulation is large, and the valve can not be affected by high-temperature expansion. Its driving momentis small and the switch is very flexible, so it is convenient to operate
