Grundfos 97627423 24V Normally Closed Actuator with End Switch

Description

The Grundfos 97627423 is a 24-volt, normally closed (NC) actuator with an integrated end switch, engineered for precise and dependable zone valve control in hydronic heating and cooling systems. Designed to meet the demands of commercial and residential HVAC applications, this actuator provides fail-safe normally closed operation, ensuring that the valve defaults to the closed position upon loss of power — a critical safety feature for protecting hydronic circuits.

Key Features

• 24V operating voltage for compatibility with standard low-voltage HVAC control systems
• Normally Closed (NC) operation — valve closes automatically on power loss for fail-safe performance
• Integrated end switch signals the system controller when the actuator has reached its fully open position, enabling accurate zone coordination
• Designed for use with compatible Grundfos zone valves in hydronic heating and cooling applications
• Reliable, long-service-life construction built to Grundfos quality standards
• Compact design for easy installation in tight mechanical spaces

Application

This actuator is ideal for use in zoned hydronic systems where individual zone control is required. The end switch feedback capability allows boilers, circulators, and system controllers to respond accurately to zone demand, improving system efficiency and comfort. The normally closed design adds an extra layer of protection against unintended flow in the event of a power interruption.
