VA-9070 Series Electric Rotary Actuators for Two-Position and Modulating Service Product
Bulletin 1
The VA-9070 Series Electric Rotary Actuators for
Two-Position and Modulating Service are designed for
direct mounting on VF Series Butterfly Valves.
The VA-9070 is available in seven different sizes, for
two-position and modulating service on VF Series
Standard-Pressure, Standard-Temperature Butterfly
Valves and VF Series High-Pressure,
High-Temperature Butterfly Valves.
For more detailed information on VA-9070 Series
Electric Rotary Actuators, refer to the VA-9070 Series
Electric Rotary Actuators for Two-Position and
Modulating Service Technical Bulletin (LIT-977325).

Table 1: Features and Benefits
Features Benefits
Low Profile and Lightweight Design Reduces space requirements and provides ease of installation.
Built-in Motor Overload Protection for 120 VAC
Motors Prevents thermal overload of motor.
Pre-wired Actuator Switches to Terminal Block;
Field-Configurable Power and Input Signals Provide ease of wiring without interference from other components;
enable field modification of input signal.
Patented Travel Limit Switch Cam Design Allows simple adjustment of travel limit cams without interference.
External Manual Handwheel Override Ensures positive and fast manual operation without the need for extra
tools or levers.
Rugged, Die-Cast Aluminum NEMA 4, 4X, IP65
Type Enclosure with Captive Housing Screws Provide waterproofing and exceptional corrosion, wear, impact, and
Ultraviolet (UV) light resistance; prevents time-consuming problems
due to lost or misplaced bolts.
Valve Status Display Provides clear and convenient indication of valve position throughout
full range of travel.
Heater/Thermostat Prevents condensation build-up and freeze-ups.
