Bard 5650-047BX - Modulating 3-Way Water Valve
The Bard 5650-047BX is an OEM modulating 3-way water control valve used on Bard hot water coil applications, where the control signal varies valve position to regulate water flow for stable discharge air temperature and smooth heating capacity. In the field, this valve is commonly paired with Bard I-TEC hot water coil setups that call for a modulating valve input (such as 0-10 VDC or 4-20 mA), helping the unit maintain comfort without the temperature swings you can see with simple on-off valves. Because it is a genuine Bard part, 5650-047BX is selected for proper fit with the intended piping arrangement and for dependable response in the control loop, which is critical when troubleshooting weak heating, hunting temperatures, or inconsistent valve movement on hydronic heat accessories.

What does the "BX" suffix mean?
Bard uses suffixes like "BX" to manage parts internally. These do not change the physical form or function of the part.
A part number ending in "BX" simply means it is packaged in a box for shipping, rather than for internal assembly use.
Example: 8406-142BX is physically identical to 8406-142.
