Siemens Building Technology 658-071 Actuator
The Siemens Building Technology 658-071 is a professional-grade Replacement Actuator with Trim engineered specifically for the Powertop 658 Series. As a Normally Open configuration, this pneumatic assembly is a critical component for technicians maintaining sequence and changeover valve operations in commercial HVAC systems. Designed for a 3/4" line size with a 6.3 Cv flow coefficient, it provides precise fluid control, ensuring optimal pressure drop and throughput for heating and cooling applications, including glycol mixtures and low-pressure steam up to 15 psig.
This 658-071 Actuator features a quick-opening characteristic, making it ideal for terminal unit control where rapid response to building automation signals is required. Built with a robust housing and specialized internal seals rated for temperatures ranging from 32° to 250°F, it stands up to the rigorous demands of mechanical rooms. For contractors, the 658-071 offers a direct-fit solution for Siemens Powertop valves, eliminating the need for complex field modifications while ensuring ANSI Class IV leakage ratings and reliable close-off performance against system pump head pressures.
Key Benefits for Technicians- Precise Flow Control: Specifically calibrated for a 6.3 Cv rating to maintain accurate system balancing.
- System Reliability: The Normally Open (N.O.) fail-safe position ensures fluid flow during pneumatic signal loss.
- Serviceability: Direct replacement trim assembly allows for faster field repairs of Siemens 658 Series valves.
- Application Versatility: Suitable for hot water, chilled water, and steam service in modern building management systems.
- Durable Construction: High-quality brass and aluminum components resist corrosion in humid mechanical environments.
- Can this actuator be used on other valve series? No, the 658-071 is specifically designed for Siemens Powertop 658 Series valves with a 3/4" line size.
- What is the typical operating pressure for this unit? Performance is optimized for standard 2-6 psi or 3-8 psi pneumatic control ranges depending on the specific valve spring used.
- Does this include the valve body? This is a Replacement Actuator with Trim assembly; the lower valve body must be present or purchased separately.
