1) radial thrust bearings, 2) non-rotating stem,

3) impactor handwheel (3 –10 times more effective than standard handwheel).

● Quick and easy repair in line.

● Seat integrally Stellited.

● Disc fully guided with Stellited seating and guiding surfaces.

● Tight shutoff.

● Stem expansion/contraction thrust unit for high temperature application (optional).
