Type 546 ball valve
A unique ball design creates a gradual change in flow direction, unlike the sudden change typical with traditional ball-valve styles. With each turn, the flow increases or decreases linearly, rather than exponentially, which provides better control. The new ball design, available as an option of the new Type 546 ball valve, features all-plastic construction, with material choices that include polyvinyl chloride (PVC), chlorinated PVC, polypropylene and polyvinylidene fluoride. Manual and actuated versions are available in sizes from 1/2-in. to 2-in.
