Siemens SSD Electronic Valve Actuators: Precision Control for Pressure Independent HVAC Systems

Description: Siemens presents the SSD Electronic Valve Actuators, designed for precise control and seamless integration with Pressure Independent Control Series Valves in heating and cooling HVAC applications. Available in both Spring Return and Non-Spring Return configurations, these actuators deliver reliable performance and energy-efficient operation, ensuring optimal control of valve positions in various HVAC systems.

Key Features:

1. Control Signal Compatibility:

  • The SSD81… series accepts a floating control signal, while the SSD61… series is compatible with proportional 0 to 10 Vdc signals, offering versatility to meet diverse control requirements.

2. High Performance:

  • With a nominal force exceeding 56 lbs (250 N), these actuators provide robust and reliable operation, ensuring precise control of valve positions for optimal HVAC system performance.

3. Automatic Stroke Calibration (SSD61…):

  • The SSD61U actuator features automatic stroke calibration, simplifying setup and ensuring accurate valve positioning without manual adjustments.

4. UL Listed for Plenum Installation:

  • These actuators are UL listed for plenum installation, guaranteeing compliance with safety standards and regulations for use in HVAC systems.

5. Reduced Power Consumption:

  • In the holding position, these actuators exhibit reduced power consumption, promoting energy efficiency and minimizing operating costs over the long term.

6. Easy Installation:

  • Direct coupled installation without the need for tools allows for quick and hassle-free setup, with hand-tightened connections ensuring secure attachment to compatible valves.
  • Manual override functionality enables manual operation when necessary, providing flexibility and convenience during system maintenance or troubleshooting.
  • Visual position indication enhances monitoring and diagnostics, allowing users to easily verify the current position of the valve.

Application:

  • Ideal for use in heating and cooling HVAC applications with Pressure Independent Control valves, these actuators are suitable for chilled/hot water systems or water-glycol solutions up to 50% in closed-loop systems.
  • The Spring Return SSDx1.5U Series actuators accommodate plenum cable or 3/8-inch flex conduit connections, offering flexibility for various installation requirements and environments.
