Frequently Asked Questions
What does the “.24(220)” in VA40.24(220) signify?
The “VA40” designates that the assembly uses a Siemens SQM40 actuator. The “.24” specifies its high-torque running profile: it operates with a 25-second runtime (for 90 degrees) to deliver a massive 90 in-lbs of turning torque. Crucially, the “(220)” indicates that this specific motor is wound for 220V/230V AC operation, rather than standard 120V.
What do the “C” suffixes mean in these part numbers?
A “C” typically denotes a specialized conformal coating on the internal electronics of the actuator, designed to protect the circuit board in high-humidity or mildly corrosive industrial environments.
What is the difference between VKF, VKP, and WBV valves?
These represent different Siemens Combustion valve body configurations. VKF valves are flanged butterfly valves, VKP valves are proportional flow control valves for highly precise linear adjustments, and WBV valves are ultra-compact Wafer Butterfly Valves designed to be sandwiched between standard pipe flanges to save space on large-diameter lines.
What are the “NF”, “NM”, “NR”, “RF”, “RM”, and “RR” designations?
These codes identify Premix Blower Adapters (PBAs). These specific VA assemblies use a specialized manifold designed to introduce and balance fuel gas directly into an air stream immediately prior to a premix blower, ensuring a perfect stoichiometric mix.
Do these assemblies require manual linkage calibration?
No manual linkage calibration is needed. Because they are pre-assembled with rigid brackets and direct couplings, mechanical backlash is eliminated. However, electronic stroke limits and fuel curves must still be programmed within your specific Siemens Burner Management System (e.g., LMV3/LMV5).
