Siemens Building Technology 656-0009 Valve
The Siemens Building Technology 656-0009 is a high-performance pneumatic mixing valve designed for precision control of hot water, chilled water, and low-pressure steam in terminal unit applications. Featuring a 1/2" flare connection (OD SAE), this normally-open 3-way assembly is a staple for veteran techs servicing fan coil units, radiation systems, and reheat coils. This Powermite 656 series valve operates within a 10-15 psi spring range, a critical technical spec for ensuring proper modulation in complex HVAC systems. With a 2.5 Cv flow rate, it provides the necessary capacity for effective mixing valve applications while maintaining a compact footprint for tight mechanical closets and restricted-access enclosures. The bronze forging and stainless steel stem are engineered to withstand the rigors of high-rise building pressure, making this Siemens pneumatic actuator assembly a reliable choice for professional HVAC valve replacement and maintenance.
Key Benefits- Enhanced Durability: Constructed with a high-grade bronze forged body and stainless steel valve stem to resist corrosion and minimize friction during HVAC system cycles.
- Precision Control: Specifically designed 3-way mixing action with a 10-15 psi spring range allows for fine-tuned temperature regulation in fan coil units.
- Ease of Installation: The compact design and rotatable pneumatic actuator facilitate fast piping connections from any direction in restricted space applications.
- High Close-off Reliability: Features a dual-sealing packed design, providing superior performance in the higher-pressure environments often encountered in commercial heating and cooling systems.
Is the Siemens 656-0009 compatible with steam systems?
Yes, this valve is rated for both water and low-pressure steam, making it highly versatile for various terminal unit applications including convectors and reheat coils.
How do I connect the pneumatic air line?
The unit includes a 1/8" NPT female pilot port. The pneumatic actuator housing can be rotated to accommodate air supply lines from different angles without removing the valve body.
What is the fail-safe position of this mixing valve?
This specific assembly is configured as normally open (NO) to the throttling port and normally closed (NC) at the bypass port for standard 3-way mixing logic.
