SHUANGLIN VALVE NO Thermal Electric Actuator – Normally Open Control

The SHUANGLIN VALVE NO thermal electric actuator is designed for applications where the default system state must remain open. In its non-energized condition, the actuator keeps the valve open, allowing continuous water flow.

This type is often used in systems where safety logic or system design requires uninterrupted circulation unless actively closed by a control signal.

When power is applied, the actuator gradually closes the valve using thermoelectric expansion technology, ensuring smooth and controlled movement without hydraulic shock.

The IP54 housing ensures reliable operation in HVAC environments, while the M30×1.5 thread provides compatibility with standard manifold systems.
