The TAC Forta™ three-model product family is designed to work with two-and three-way globe valves ranging in size from 1/2 to 6 in. Features include "One Touch" programming capability, which enables endusers to automatically set up and install a Forta actuator quickly and an automatic scaling feature that eliminates most of the setup time required to scale the actuator's input signal to match different valve stroke lengths.
