Leakage after closing UNICON:0.9L(measured actually) Ball Valve:more than UNICON due to its slow shutoff speed

UNICON employs Multi-Spring in Actuator. UNICON can solve the backlash problem at the connection part. Ball Valve results in much higer hysteresis due to backlash at the ball and stem.

Wafer Type

Double Flange Type

Complete Bi-directional Sealing. Double Seat eliminates deforming or damaging under high differential pressure and high fluid velocity.

The disc moves entirely away from the seat at all points in the very few degrees. This assures a long seat life.

UNICUT prevents abrasion and wear that may occur between disc and metal seat. This assures a longer sealing life.

TA-LUFT Approved. It prevents external leakage from the gland. Double sealing allows maintenance free.

Seat replacement can be done very easily and quickly without disassembling the shaft and disc.
