Henan Shangfa Valve Co., Ltd

Manual ventilation butterfly valve is used in dust-bearing cold wind or hot air pipelines of chemical engineering, building materials, power station, glass and other industries as control device to regulate flow rate or cut off gas medium. It is installed in pipelines with medium temperature ≤ 300 ℃ and nominal pressure of 0.1 Mpa to connect, open or close or adjust medium. The valve should be generally installed horizontally in the pipelines.

The sealing ring of ventilation butterfly valve use same material as body and its applicable temperature is determined by material selection of valve body. Its nominal pressure ≤ 0.6 0.6MPa and generally suitable for industrial, metallurgical, environmental protection pipelines to regulate medium flow.

 Its main features are:

1. New, reasonable design, unique structure, light weight, quick opening and closing.

2. Small operating torque, easy operation and labor-saving dexterity.

3. Adopt suitable materials to meet different medium temperature and corrosive medium, etc..

4, See the instructions for the principle of actuator, wiring diagram, technical parameters.

5. The valve can be made according to customer's request (please indicate the angle in the contract when not horizontal installation).

6. Please indicate in contract if accessory needed.

Manual ventilation butterfly valve is made of steel plate welded structure, it has the characteristics of small size, light weight and easy installation, and it will not be affected by high temperature expansion because of its small flow resistance and large flux. Its drive torque is small, the switch is very flexible, and so it is very convenient to operate.
