VA9335-HGA-2 Johnson Controls Actuator

Overview

The Johnson Controls VA9335-HGA-2 is a non-spring return electric valve actuator designed to provide reliable proportional, floating, or on/off control for valves with an ISO flange mounting, such as the VG1000 Series ball valves. It features automatic signal input detection, allowing the device to automatically recognize and adapt to the controller signal type.

Features

• Automatic signal input detection for on/off, floating, and proportional control
• Self-calibrating input signal to adjust the stroke automatically
• Microprocessor-controlled brushless DC motor provides constant runtime independent of torque
• Electronic stall detection protects the motor from overload across the entire rotation range
• Mode configuration DIP switches permit easy calibration, input signal range selection, and control logic reversal
• Integral 1.2 m halogen-free appliance cable with colored and numbered conductors simplifies field wiring

Specifications

• Torque: 310 lb-in (35 N·m)
• Supply Voltage: Nominal 24 VAC/VDC
• Control Signals: Proportional (0 to 10 VDC or 2 to 10 VDC; 0 to 20 mA or 4 to 20 mA with a 500 ohm resistor), Floating, or Two-Position
• Feedback Signal: 0 to 10 VDC or 2 to 10 VDC position indicator
• Rotation Time: 150 seconds
• Enclosure Rating: NEMA 5 / IP54
• Operating Temperature Range: -22°F to 140°F (-30°C to 60°C)

Applications

• Designed for direct-coupled mounting on HVAC valves with an ISO flange interface, such as Johnson Controls VG1000 Series ball valves from 2-1/2 inches to 6 inches.
• Suitable for building automation systems and loops requiring precise proportional water or steam flow regulation under standard commercial operating conditions.
