VA9208-GGA-2 Johnson Controls Actuator

Overview

The Johnson Controls VA9208-GGA-2 is a professional-grade spring return electric valve actuator designed to provide accurate proportional modulation of VG1000 Series 1-1/4, 1-1/2, and 2 inch ball valves in HVAC systems. It is engineered for bidirectional, direct-coupled mounting and features a mechanical spring-return system to ensure the valve moves to a defined failsafe position upon power interruption. Specially configured with a plenum-rated cable, it meets strict fire safety requirements for installation in environmental air-handling spaces.

Features

• Spring-return mechanical safety system provides reliable fail-safe operation
• Multi-signal input compatibility reduces inventory complexity across systems
• Direct-coupled mounting simplifies installation and eliminates mechanical play
• External mode selection switch allows easy configuration
• Feedback signal (0-10 VDC or 2-10 VDC) indicates position and supports master-slave setups
• Equipped with a 120-inch plenum-rated cable with an integral 3/8-inch FMC connector
• Robust construction with a minimum expectancy of 200,000 full cycles
