When the original Camflex was introduced in 1968 it created a revolutionary new category of control valves -the Rotary Globe. This new type of valve converged the best control features of a conventional globe valve with a rotary action to produce a versatile valve with several advantages over the glob valve. But why the name?
CAM-flex
The heart of the Camflex valve is its eccentric plug. The eccentrically rotating, double offset plug CAM’s into and out of the seat. This camming action eliminates friction throughout its rotation since the plug moves away from the seat as it opens, unlike other rotary valve types. This ensures precise control at all openings.
Cam-FLEX
The plug is offset such that the trailing edge of the plug face will contact the seat ring first when closing. Additional plug rotation causes the plug arms to flex slightly, moving the plug face into full contact with the seat. This flexing action ensures tight long-term seating with smooth seating/unseating action.
