• Integrally cast mounting pad provides direct mounting of Keystone actuators.

• Rocker-shaped gland bridge compensates for uneven adjustment of gland nuts.

• Extended neck allows for two inches of pipeline insulation.

• Flattened body bore at stem journal ports positions stem bearings near disc, providing maximum 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.
