VA7810-HGC-2 Johnson Controls Actuator

Overview

The Johnson Controls VA7810-HGC-2 is a heavy-duty, non-spring return electric globe valve actuator designed to provide precise flow control in commercial HVAC and building automation systems. It features a direct-coupled design for quick installation and offers fail-in-place operation, maintaining its last position upon a loss of power.

Features

• Direct-coupled mounting eliminates the need for complex linkage hardware.
• Non-spring return function ensures the actuator holds its position during power outages.
• Manual override allows for simple positioning during commissioning or emergency situations.
• Built-in two SPDT auxiliary switches provide end-of-travel feedback or system interlocking.
• Brushless motor design ensures low energy consumption and an extended service life.
• Multi-signal input capability reduces the need for multiple actuator variants.
