VA9203-BUA-2 Johnson Controls Actuator

Overview

The Johnson Controls VA9203-BUA-2 is a direct-mount, rotary electric spring-return valve actuator designed for bidirectional operation. It operates on a wide supply voltage range from AC 85 to 264 V at 50/60 Hz and provides two-position (on/off) control. It is engineered to deliver reliable and precise positioning for ball valves within environmental control systems.

Features

• Direct-coupled mounting for simplified installation without additional linkages.
• Mechanical spring return fail-safe system ensuring secure closure or opening during power loss.
• High life expectancy engineered for a minimum of 200,000 full-cycle operations.
• Robust construction featuring a NEMA 2 (IP54) rated enclosure.
• Built-in international compliance supporting UL, CE, and C-Tick regulatory agency approvals.
