The Marwin Valve Actuator Sizing Program enables the user to select any of the Marwin ball valve series, size, seat material and service factor from several drop-down menus. The program will calcuate the proper size Marwin electric and pneumatic actuators (and gear operators) for the valve selected. The program has a built-in database of all necessary Marwin valve and actuator parameters.

In addition, a special feature allows the user to input their own operating torque for non-Marwin valves. The program matches the variable torque of the valve stroke to that of spring return actautors.

An instruction page is included in the program, along with appropriate defaults and messages.
