Belimo ZONE120NO Spring-Return Zone Valve Actuator, Normally Open, 120VAC

Description

Belimo ZONE120NO Spring-Return Zone Valve Actuator Overview

The Belimo ZONE120NO is a spring-return zone valve actuator engineered for dependable, energy-efficient HVAC zoning applications. Designed to operate at 120VAC, this normally open actuator ensures that the controlled zone remains open in the de-energized state — providing a fail-safe condition that protects heating and cooling systems during power interruptions. The spring-return mechanism automatically returns the actuator to its normal position upon loss of power, making it an ideal choice for residential and light commercial hydronic heating, fan coil, and air handling systems.

Key Features

• Spring-return operation for automatic fail-safe positioning on power loss
• Normally open (NO) configuration — valve opens when de-energized
• 120VAC operating voltage for compatibility with standard HVAC control circuits
• Compact, lightweight design for easy installation in tight spaces
• Direct-mount design eliminates the need for additional linkage or adapters
• Quiet operation suitable for residential and occupied commercial spaces
