1 TAC 1354 Clifford Avenue P.O. Box 2940 Loves Park, Illinois Two-Way and Three-Way Globe Valve Assemblies with 220 lbf Linear (979 N) Spring Return DuraDrive Actuators Submittal Sheet VA, VF, and VS Series Direct Mounted Globe Valve Assemblies The Invensys VA, VF, and VS-XXXX-5XX series direct mounted, two-way and three-way globe valve assemblies are complete actuator/valve assemblies that accept two position, floating, or proportional control, respectively, from a DDC system or from a thermostat, for control of hot water, chilled water, and steam applications. These valve assemblies consist of spring return linear actuators direct mounted to 1-1/ 4" through 4" (32 mm through 100 mm) two-way and three-way globe valve bodies. An integrated rack and pinion translates the rotary motion of the actuator into the linear motion of the valve stem. Application Typical applications include hot and chilled water coils in air handling units, and unit ventilators. Features ISO 9001 Certification Thermal isolation 3 ft.
