One: brief introduction of pneumatic ventilating butterfly valve
       The pneumatic ventilating butterfly valve is made of the same material as the valve body and is sealed with electric or pneumatic transmission. The suitable temperature and body material, nominal pressure is less than 0.6MPa, suitable for general ventilation for regulating media flow in industry, metallurgy, environmental protection and other pipeline.

Two: Main features of pneumatic ventilating butterfly valve
1, The design is novel, reasonable, unique in structure, light in weight and fast in opening and closing.
2, small operating torque, easy operation, labor-saving and smart.
3, the use of suitable materials to meet low, medium and high temperature of different media and corrosive media.

Three: Pneumatic ventilating butterfly valve adopts standard

Design standard: GB/T12238-1989 JB/T8692-1998
Flange size: GB/T9115.1-2000
Structure length: GB/T12221-1989
Pressure test: GB/T13927-1992; JB/T9092-1999

Four: Pneumatic ventilating butterfly valve actuating mechanism

       Using GT or AT series pneumatic actuator, double action and single action (spring), gear drive, safe and reliable; large diameter valves using AW pneumatic actuator fork transmission, reasonable structure, large output torque, a double acting and single acting.\
1, Gear type double piston, the output torque is large, small size.
2, GT/AT pneumatic actuators using aluminum alloy material, light weight, beautiful appearance.
3. Manual operation mechanism can be installed at top and bottom.
4, Rack type connection can adjust the opening angle and rated flow.
5, GT/AT pneumatic actuator optional live signal feedback instructions and various accessories to achieve automatic operation.
6, IS05211 standard connection for the installation of products to replace the convenience.
7, Adjustable ends of the screws can make the standard products at 0 degrees and 90 degrees, there is an adjustable range of + 4 degrees. Ensure the synchronization accuracy with the valve.

Five: pneumatic ventilation butterfly valve attachment options

The following attachments can be selected according to different controls and requirements:
Cut off type accessories: single electric controlled electromagnetic valve, double electronically controlled solenoid valve, limit switch back detector.
Adjustable accessories: Electrical positioner, pneumatic positioner, electrical converter.
Air source treatment accessories: air filter pressure reducing valve, gas source treatment triple parts.
Manual mechanism: HVSD hand operated mechanism.
