2 Way & 3 Way Actuated Ball Valves

Unimizer® 2 & 3 Way Actuated Ball Valves

Sizes 1/2″ – 6″

2 Way & 3 Way Actuated Ball Valves
Accuracy: The Unimizer® eliminates inaccuracy in ball valves. This is made possible with the technology of the Griswold parabolic flow OPTIMIZER®, a device inserted into the ball to achieve Equal Percentage Control Characteristics.

Lower Cv Ratings: Why choose a ball valve over a globe valve? With the Unimizer® you can achieve the low Cv ratings of a globe valve at the low price of a ball valve. You can get the added benefit of higher close off pressure.

Compatibility: The Unimizer® is available in Female or Sweat threaded end connections. The Unimizer® sets the standard for compatibility, and Griswold’s Universal Solution offers the widest range of actuator choices in the industry.
Griswold Controls’ Patent Pending 3-Way Ball
Griswold Controls’ Patent Pending 3 Way Ball: Many manufacturers settle for providing non-equal percentage control to the coil, or they achieve equal percentage control by using a costly, custom programmed actuator. Griswold Controls’ Unimizer® achieve true equal percentage flow from the parabolic shape of the Optimizers® located at each port, thereby allowing the use of any standard, low cost actuator.

Recommended Applications:

  • Where actuated ball valves or globe valves are used to control the flow
  • Where mixing and diverting capabilities are required
  • For hotels & schools; air handling units, equipment rooms, and pipeline products
