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.

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.
