Watts 1800839 Actuator

The Watts 1800839 Actuator is a professional-grade 115V electric valve actuator engineered for precise automated control of quarter-turn ball valves. Also identified by industry part numbers 0424415 and EA350-115, this unit is a standard in commercial and industrial HVACR systems where reliable fluid management is critical. Featuring a 35-second cycle time, the 35S EA350 series provides the torque necessary to rotate valve stems consistently under pressure without the jerky movements common in lower-grade alternatives.

Built for veteran contractors, the Watts EA350 facilitates easy field installation with a robust housing and high-visibility position indicators. This quarter-turn ball valve actuator is designed to reduce system downtime by providing a seamless electrical interface for 115V AC loops. Its compatibility with various Watts ball valve bodies makes it an essential component for technicians managing boiler systems, radiant heating, and cooling water circuits. By utilizing this electric valve actuator, you ensure accurate flow modulation and long-term mechanical stability in high-demand environments.

• Direct Interchangeability: Fully replaces legacy part numbers 0424415 and 424415, simplifying inventory and field repairs.
• Optimized Duty Cycle: The 35-second travel time prevents water hammer issues while maintaining responsive flow control.
• Rugged Construction: Designed for duty in mechanical rooms with resistance to common environmental stressors.
• Simplified Wiring: Standardized 115V AC power requirements integrate into most existing BMS and control circuits.
• Visual Diagnostics: Integrated position indicator allows for rapid visual verification of valve status during inspection.

• What causes this actuator to fail? Most failures are due to electrical surges, moisture ingress from poor conduit sealing, or torque overload caused by a seized ball valve.
• Can I manually override the actuator? Many EA350 models include manual override capabilities to move the valve during power loss or commissioning.
• Is this compatible with 24V systems? No, this is a dedicated 115V actuator. Wiring it to a 24V source will result in a failure to move, while higher voltage will damage the internal motor.
