ZXQ01 Normally Closed Electric Actuator – Compact Spring-Return Fail-Safe Automation for Small Valve Applications

The Coliter® ZXQ01 Normally Closed (NC) Electric Actuator is a compact, spring-return actuator engineered for fail-safe control of small ball or butterfly valves in residential, HVAC, and light industrial systems. In the event of power failure, its integrated spring mechanism automatically returns the valve to the closed position, preventing unintended flow—ideal for applications such as boiler safety cutoff, pump isolation, or domestic water shut-off. With an output torque of 5 Nm, it supports both 24V DC and 220V AC power options and features simple on/off (2-point) control with a built-in manual override for maintenance or emergency operation. Enclosed in a lightweight yet robust aluminum alloy housing rated IP67, the ZXQ01 offers excellent protection against dust and water ingress. Compliant with ISO 5211 mounting standards, it integrates seamlessly with smart thermostats or building automation systems—delivering reliable, energy-efficient, and safe valve control in compact installations.
