ACT VA-3100-HGC PROP; ELECTRIC VALVE ACTUATOR 675 LBS 24 VAC PROPORTIONAL W/SWITCHES

Description

VA-3100 Series Electric Valve Actuators use a synchronous motor to accurately position Johnson Controls® VG2000 Series Cast Iron Flanged Globe Valves in HVAC and industrial applications. These non-spring-return electric actuators have a 675 lb (3,000 N) force output for on/off (floating) or proportional control. Integral auxiliary switches are available to indicate end-stop position or to perform switching functions. Position feedback is also available through an isolated 2,000 ohm potentiometer. All models feature a manual hand crank for manual positioning of the valve, independent of a power supply.

Refer to the VA-3100 Series Electric Valve Actuators Product Bulletin (LIT-977283) for important product application information.

Features

• synchronous motor with pressure switches

• provides a constant running speed and establishes fixed closeoff forces

• two-bolt coupler clamp provides quick and easy coupling of the actuator to the valve stem

• on/off (floating) or proportional control allows optimal choice of control signal

• adjustable starting point, span, and action (proportional control model only) provides application flexibility and allows for easy sequencing from only one output signal

• 0 to 10 VDC position feedback signal (proportional control model only) provides accurate valve position indication in response to an input signal up to 10 VDC

• auxiliary switches and feedback potentiometer available on select models provide independent verification of actuator position

• manual hand crank allows for manual positioning of the valve, independent of a power supply
