Product Description

The SA91 Normally Open (NO) Electro-thermal Actuator is engineered for precise flow regulation in Fan Coil Unit (FCU) systems. Utilizing a high-quality wax element drive, it provides smooth, silent ON/OFF control when paired with a compatible M30 x 1.5mm zone valve. Its ultra-low 2W consumption and wide 100–240VAC voltage range make it an energy-efficient and universally adaptable choice for intelligent HVAC zoning solutions, ideal for integration with major BMS.

Key Functions

Precision Zonal Control

Regulates water flow to individual FCU coils based on thermostat signals, ensuring optimized and personalized room temperature management.
Maintain Fail-Safe Flow

As a Normally Open (NO) device, the valve remains open when power is lost, maintaining critical flow during control system failure or power outage.
Universal Thread Fit

Features the industry-standard M30 x 1.5mm connection, guaranteeing seamless and rapid integration with most common Zone Control Valve bodies.

Robust Environmental Shield

IP45 rated housing provides reliable protection against dust and water splashing, making it durable for internal FCU cabinet installation.
Silent Operation / Quiet Control

The wax element drive ensures smooth, gradual, and virtually silent switching, ideal for noise-sensitive commercial environments like hotels.
Fast System Diagnosis

Built-in visual indicator offers immediate confirmation of the actuator's open or closed status, simplifying maintenance and troubleshooting efforts.
