Sizes: 1/2" - 3"
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 - 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.
