6 10 Wafer Style Butterfly Valve / Food Grade Exhaust Butterfly Valve

 

Wafer Style Butterfly Valve introduction:

 

Double  end flanged resilient sealing butterfly valve is operated by the disc rotating form 0° to 90°, can be applied to cut off or regulate the flow of medium.

Wafer Style Butterfly Valve is a type of flow control device, typically used to regulate a fluid flowing through a section of pipe.
The valve is similar in operation to a ball valve. A flat circular plate is positioned in the center of the pipe.
The plate has a rod through it connected to an actuator on the outside of the valve. Rotating the actuator turns the
plate either parallel or perpendicular to the flow. Unlike a ball valve, the plate is always present within the flow,
therefore a pressure drop is always induced in the flow regardless of valve position.
