Pneumatic Ventilating Butterfly Valve

First, 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 drive. 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 structure, light weight, quick opening and closing.
2, Small operation torque, easy operation, labor-saving and smart.
3, The use of suitable materials to meet the low, medium, high temperature of different media and corrosive media.

Three, Pneumatic Ventilation Butterfly Valve Adopts Standard
Design Standard: GB/T12238-1989 JB/T8692-1998
Flange Connection Size: GB/T9115.1-2000
Structure Length: GB/T12221-1989
Stress 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 big, small volume.
2, GT/AT pneumatic actuator using aluminum alloy material, light weight, beautiful appearance.
3, Manual operation mechanism can be installed on top and bottom.
4, Rack type connection can adjust opening angle and rated flow.
5, GT/AT pneumatic actuator optional charged signal feedback instructions and various accessories to achieve automatic operation.
6, IS05211 standard connection provides convenience for installation and replacement of products.
7, Adjustable screws at both ends can make the standard products at 0° and 90° Adjustable range of  ±4°. Ensure the synchronization accuracy with the valve.

Five, Pneumatic Ventilation Butterfly Valve Accessories Options
The following accessories can be selected according to different control and requirements:
Cut off accessories: single electronic controlled solenoid valve, double electronic controlled solenoid valve, limit switch return device.
Adjustable accessories: Electrical positioner, pneumatic positioner, electrical converter.
Air source treatment accessories: air filter pressure reducing valve, gas source treatment sanlian.
