Butterfly Valves
GEA manufactures two types of butterfly valves: wafer style (02 series) and demountable (03 series), which is assembled via sanitary Tri-Clamps. All valves can be supplied with either pneumatic actuators or manual handles, or with locking pins to fix the valve position.
The valve is used to isolate or regulate flow. The disc is positioned in the center of the pipe and, passing through the disc, is a rod connected to an actuator on the outside of the valve. Rotating the actuator turns the disc either parallel or perpendicular to the flow. Unlike a ball valve, the disc is always present within the flow; therefore, a pressure drop is always induced in the flow, regardless of valve position.
The “butterfly” is a metal disc mounted on a rod. When the valve is closed, the disc is turned so that it completely blocks off the passageway. When the valve is fully open, the disc is rotated a quarter of a turn so that it allows almost unrestricted passage. The valve may also be opened incrementally to regulate product flow.Products
