Pneumatic Ventilation Butterfly Valve

Features & Benefits

Ventilation butterfly valve uses the aluminum alloy material as the valve body to process the seal ring and adopts electric or pneumatic actuator.
The applicable temperature depends on the valve body selection, nominal pressure ≤0.6MPa, generally applicable to industrial, metallurgical, environmental protection and other pipelines for ventilation regulation media flow use.
Ventilation butterfly valves are used in the dusty cold air or hot air gas pipelines in the ventilation and environmental protection projects in the chemical, building materials, power stations, and glass industries, as a gas medium to regulate the flow or cut off the pipeline control devices.
This type of valve should generally be installed horizontally in the pipeline.
When the ventilating butterfly valve is in the fully open position, the thickness of the ventilating disc is the resistance when the medium flows through the valve body, so the pressure drop generated by the valve is very small, so it has better flow control characteristics.

Product Description

All listed output torques are expressed in inch pounds of torque (in. lbs.).
Charts for available air pressure are expressed in pounds per square inch (P.S.I.).
FLOWX actuators offer ±5° adjustment in the open and closed positions on DA52 through DA-125 models.
For all other models, adjustment is in the open position only.
The closed position is 0° fixed. Optional retrofit kits are available to allow for adjustment in both open and closed positions on the DA-160, DA-200 and DA-270 models.

General Application

Ideally suited for many applications within the heating ventilation and air conditioning, water treatment and irrigation markets.
