Datasheet

Features

• 500 N force output in compact unit
• Magnetic clutch
• Unique Yoke Design
• Coupler for simple actuator attachment to flanged valves
• Positioner with adjustable startintg point and span, reverse and direct action modes
• Signal fail safe position

Overview

The 146350P1S Liebert Mod Motor is a high-performance electric valve actuator designed for precise airflow and fluid management within Liebert HVAC systems. As a direct replacement for the Johnson Controls VA-7153-5001, this reversible synchronous motor-driven unit is engineered to transform electrical energy into mechanical force, enabling the accurate opening and closing of air dampers and valves. It is a critical component for maintaining consistent climate control in sensitive environments such as data centers.

Features

• Magnetic clutch provides constant output force and protects the motor in stall conditions
• Unique yoke design allows for easy field mounting and reduced installation time
• Compact unit delivers a high force output of 90 lb (500 N)
• Selectable direct and reverse action simplifies system setup
• Positioner features adjustable starting points and span modes
• Signal fail-safe position automatically moves the stem to a pre-selected safety position
• Durable bronze and aluminum construction ensures a long cycle life
