Information About ML7421A1032
The ML7421A1032 is a Honeywell ML7421 Series non-spring-return actuator engineered for direct mounting on compatible linear-stroke globe valves. Its synchronous motor and electronic positioning system provide modulating valve control, while the high 405 lbf output force supports demanding applications including pressure-balanced VGF valves. Direct coupling eliminates separate linkage and associated linkage adjustments, and the integrated manual operator allows valve positioning during installation or service. Force-limiting end switches, low power consumption, approximately 95-second nominal drive time, and compatibility with 3/4-inch stroke valve assemblies make the actuator suitable for hydronic and steam control in air-handling, heating, cooling, and building automation systems.
Key Features:
- 405 lbf rated force: Provides approximately 1800 N of linear force for reliable positioning and high valve close-off capability.
- Non-spring-return operation: Electrically drives the valve without an automatic mechanical spring-return function.
- Modulating control: Provides proportional valve positioning from a compatible DC control signal.
- 24 VAC power: Operates from standard low-voltage power commonly used in commercial HVAC control systems.
- Direct-coupled mounting: Installs directly onto compatible Honeywell globe valves without a separate linkage assembly.
- Globe valve compatibility: Designed for compatible V5011, V5013, and VGF Series flanged globe valves.
- Synchronous motor: Provides controlled and repeatable linear actuator movement for precise valve positioning.
- Force-limiting end switches: Limits actuator force at the ends of travel to protect the actuator and connected valve.
- Manual operator: Integrated manual control permits valve positioning during commissioning and service.
- 95-second nominal runtime: Provides controlled valve travel with approximately 95-second drive timing at 60 Hz.
- High-temperature media application: Suitable for compatible hot-water and steam valve applications with media temperatures up to approximately 300°F.
- Maintenance-free design: Designed for long-term HVAC service without routine internal actuator maintenance.
The ML7421A1032 delivers the reliability and precision required for modulating chilled-water, hot-water, and steam valve control in commercial HVAC systems.
