Siemens SSD131.09U 3-Position (Floating) Valve Actuator – 300 N, AC 24V, Fail-in-Place

The Siemens SSD131.09U Actuator is an OEM 3-position floating (non-modulating) valve actuator designed for Pressure Independent Control Valves (PICV) with a 5- or 5.5 mm stroke. It operates on AC 24V and delivers ~300 N (≈ 67 lb) nominal force. Equipped with a manual override, LED position indicator, and UL listing for plenum use, the SSD131-09U is ideal for demanding HVAC / building automation applications.

Key Features

• 3-position floating control with fail-in-place design

• Operates on AC 24V input for standard building automation systems

• Provides 300 N nominal force for dependable valve operation

• Compatible with Siemens PICV valves with 5 / 5.5 mm strokes

• Manual override for setup, testing, and maintenance

• LED visual indicator shows actuator position in real time

• UL-listed and approved for plenum installations

Technical Specifications

Applications

• Used with Siemens PICV valves in hot/chilled water systems to control flow precisely.
• Terminal units, VAV boxes, fan coils, chilled ceilings, etc., where floating control is used.
• Systems requiring plenum-rated components or visibility of actuator position via LED.
• Replacement or upgrade for older actuators in floating control circuits.

Installation & Best Practices

• Connect to a controller capable of 3-position floating signals (Y1/Y2)

• Mount directly to compatible Siemens PICV valves with quick coupling

• Use the manual override for setup and maintenance

• Confirm operation with the LED position indicator after wiring

• Avoid exposure to conditions outside Siemens’ specified ranges
