Siemens Building Technology 656-600 Valve Actuator
The Siemens 656-600 is a heavy-duty pneumatic valve actuator replacement top designed for seamless integration with Siemens Powermite series valves. This replacement actuator with trim is engineered for 3/4" line sizes and features a normally open (NO) fail-safe position, ensuring the valve remains open upon loss of control air. Built for precision in pneumatic HVAC controls, the 656-600 operates on a standard 3-8 psi spring range, providing reliable modulation for terminal unit applications such as fan coils, baseboard radiation, and reheat coils. The assembly includes a complete operating top and internal trim, allowing for efficient field repairs without a full valve replacement. Its 0.9 Cv rating and 4.6 Cv flow capacity (depending on valve body pairing) ensure consistent performance in demanding commercial environments. As a veteran-grade HVAC replacement part, it offers a direct fit for 656-0005 and 656-0018 valve bodies, maintaining the mechanical integrity of your existing building automation system (BAS).
Key Benefits for the Contractor:- Precise Modulation: Reliable 3-8 psi spring range calibrated for standard pneumatic control signals.
- Normally Open Configuration: Mechanical spring return ensures maximum safety and flow during air failure.
- Complete Replacement Kit: Includes the actuator top and trim assembly to restore full functionality to 3/4" Powermite valves.
- Durable Construction: Designed by Siemens Building Technology for longevity in high-cycle terminal unit environments.
- Efficient Field Repair: Minimizes system downtime by allowing for a top-down assembly swap without removing the valve body from the line.
Is the 656-600 compatible with older Powers Powermite valves?
Yes, this unit serves as a direct replacement for 3/4" Powers Powermite and Siemens 656 series valve tops, specifically for normally open 3-8 psi applications.
Does this include the valve body?
No, the 656-600 is a replacement actuator top with internal trim. It is intended to be mounted onto an existing 3/4" valve body already installed in the piping.
What is the maximum control air pressure for this actuator?
While the operating range is 3-8 psi, the casing is generally rated to handle up to 30 psi, but always consult your specific system's air station limits to prevent diaphragm damage.
