1. High range ability
2. Big reduction in size
   The hydrodynamic configuration of the disc keeps the flow resistance at a minimum level when the valve is fully open. This valve has twice the CV of glove valves.
3. The body is slim, lightweight and compact.
4. Clearance between body and disc
   Although it is a damper type, it has a low leakage structure （ 0.5 to 2% of rated CV）. Stable control is effected allowing the fitting of a compact actuator.
