Special Features:

Lflattened body bore at stem journal ports position stem bearings near disc, providing max stem support; disc taper pins are tangentially positioned half in disc and half in stem, placing them in compression rather than shear, which eliminates potential for failure; two piece stem design allows for highcycling and creates a lower disc profile with increased capacity and a rangeability of 33: 1; polymer seat incorporate a stainless steel braided wire winding, enclosed in a u shape envelope to provide seating energy and memory, thiswire winding allows axial flexibility in both directions of flow, also allowsradial flexibility when the disc is not fully closed, reducing seat/disc interference, seat wear and stem torque

Properties:

A valve that controls flow by a circular disk, or a pair of semicircular disks, attached to a common spindle or lever turning on a diametral axis.
