SEO Meta Description: Discover the Royal Apex Siemens Sfa 21/18 Electric Motor Actuator, a reliable and durable product made in Korea. This electric actuator is designed for controlling zone valves and offers spring return and manual adjustment features.
Introduction
The Royal Apex Siemens Sfa 21/18 Electric Motor Actuator is an essential component for controlling zone valves in various applications. It is designed to provide precise and efficient control over the valve’s opening and closing, ensuring optimal performance and energy efficiency.
Main Features
The SFA21/18 AC 230V operating voltage ensures compatibility with standard power supplies. It offers a 2-position control signal, allowing for easy integration with on/off controllers like thermostats. The electric motor is overload-resistant and anti-locking, enabling continuous operation without any issues.
The actuator’s maximum stroke is mechanically limited, ensuring safe and reliable operation. The closing motion includes an overrun for the gear mechanism, protecting it from mechanical shock and extending its service life. The positioning force of 200N ensures precise and reliable valve control.
Spring Return
The actuator features a spring return mechanism, which allows for automatic valve closure when the control signal is cut off. This ensures that the valve remains closed when the desired temperature is reached, preventing any unwanted heat loss or gain.
Manual Adjustment
For added convenience, the actuator offers manual adjustment capabilities. It can be easily mounted with a union nut, requiring no additional tools. The valve can be opened manually using a lever on the actuator. When the valve is approximately 90% open, the lever locks into position, providing secure and stable operation. The locking mechanism is automatically released when electrical operation resumes.
Additional Features
The actuator comes with an integral 1.8m connecting cable, ensuring easy installation and connection. An optional auxiliary switch, type ASC2.1/18, is available for enhanced functionality and control.
Country of Origin
The Royal Apex Siemens Sfa 21/18 Electric Motor Actuator is proudly made in Korea, known for its high-quality manufacturing and technological expertise.
