1 VA222-xxx-2 Series Electric Spring Return Valve Actuators Product Bulletin Code No. LIT-26 Issued March 25, 28 Supersedes March, 26 VA222 Series Spring Return Electric Valve Actuators are available in 24 VAC/VDC and 2 VAC ON/OFF control, 24 VAC Floating Control, and 2 to VDC (4 to 2 ma) Proportional Control for use in Heating, Ventilating, and Air Conditioning (HVAC) applications. All models provide 8 lb. in (2 N. m) of output force and feature a NEMA 2 (IP42) housing for indoor use. Versions with a factory-installed Single Pole, Double Throw (SPDT) auxiliary switch are available. The VA222 Series actuators are designed for easy mounting in the field to /2 and 3/4 in. Johnson Controls VG Series Ball Valves. The optional available auxiliary switch is adjustable from 5to95. Table : Features and Benefits Features Proportional, Floating and On/Off Control Models Available Single Screw, Direct Mounting Optional Available Reversible Mounting Design Compact Design Figure : VA222 Series Electric Valve Actuator on VG Series Ball Valve Benefits Allows the actuator to be used in wide range of applications and optimal choice of control signal Simplifies installation Provides independent verification of actuator position Simplifies setup of valve spring return position Provides solution for limited-space applications VA222-xxx-2 Series Electric Spring Return Valve Actuators Product Bulletin

2 Application IMPORTANT: Use this VA222 Series actuator only as an operating control. Where failure or malfunction of the VA222 actuator could lead to personal injury or property damage to the controlled equipment or other property, additional precautions must be designed into the control system. Incorporate and maintain other devices such as the supervisory or alarm systems or safety or limit controls intended to warn of, or protect against, failure or malfunction of the VA222 actuator. For CW spring return operation (see Figure 2 and Table 3), mount the actuator so the CW face of the actuator (gray side) is away from the valve as illustrated in Figure 2. The actuator drives CCW and spring returns CW. IMPORTANT: This device is not designed or intended to be used in or near environments where explosive vapors or gases could be present, or environments where substances corrosive to the device s internal components could be present. All actuators can be ordered factory assembled or field-mounted to /2 and 3/4 in. VG Series ball valves. See Table 2 for information on control applications by model.
