Enhance Valve Control Efficiency with Siemens SQL321B.. and SQL361B.. Electromotoric Actuators

Description: Siemens introduces the SQL321B.. and SQL361B.. series of Electromotoric Actuators, meticulously engineered to provide precise control and reliable operation for VKF42.. and VFF41.. butterfly valves in heating, ventilation, and air conditioning (HVAC) systems. These advanced actuators offer versatile control options and robust construction, ensuring optimal performance in various applications.

Key Features:

1. Versatile Control Signals:

  • The SQL321B.. series operates on AC 220 V and utilizes a 2-position (SPDT) control signal, ideal for applications requiring simple on/off control.
  • For more sophisticated control requirements, the SQL361B.. series offers flexibility with an operating voltage of AC 220 V and support for DC 0(2)…10 V or 4…20 mA control signals, enabling precise modulation of valve positions.

2. Optional Auxiliary Switch (SQL361B150…B6000):

  • The SQL361B.. series can be equipped with an optional auxiliary switch, providing additional functionality and versatility for specific application needs.

3. Robust Design and Compatibility:

  • With a nominal angle of rotation of 90° and compatibility with EN ISO 5211 flanges, these actuators ensure compatibility and seamless integration with a wide range of butterfly valves, including VKF42.. and VFF41.. models.
  • The built-in heating element effectively prevents condensation, ensuring reliable performance even in challenging environmental conditions.

4. User-Friendly Features:

  • Each actuator is equipped with a handwheel and position indicator, facilitating manual operation and visual monitoring of valve positions, enhancing user convenience and ease of maintenance.

5. Wide Range of Applications:

  • These electromotoric actuators are designed for use in heating, ventilation, and air conditioning plants, where precise control of shutoff and control valves is critical for maintaining optimal system performance and efficiency.

Application:

  • The SQL321B.. and SQL361B.. Electromotoric Actuators are specifically tailored for HVAC systems, offering reliable and precise control over butterfly valves in various heating, ventilation, and air conditioning applications.
  • Whether in commercial buildings, industrial facilities, or residential properties, these actuators deliver exceptional performance, ensuring smooth operation and efficient management of HVAC systems.
