EMERSON Expansion Valve BAE 1 2 3 4 5 6 NW100 R22 407C

This is an Emerson BAE‑series balanced‑port thermostatic expansion valve (TXV), purpose‑built for R407C refrigerant in air‑conditioning and heat‑pump refrigeration systems. It meters and throttles high‑pressure liquid refrigerant entering the evaporator while maintaining stable superheat.

Product Information

Product Features

• Balanced‑port architecture compensates variable operating pressure from changing ambient, defrost cycles, heat reclaim and shifting evaporator loads for steady superheat regulation
• Bi‑directional flow performance supports both cooling and heating operation in heat‑pump setups with one single valve unit
• Corrosion‑resistant stainless‑steel power element prevents premature valve failure from refrigerant‑side corrosion
• Hermetic leak‑free sealed construction reduces risk of refrigerant leakage
• Compact form factor to fit tight mechanical room or unit internal mounting spaces
• External equalization design optimizes performance for evaporators with notable internal pressure drop
• Factory pre‑charged for R407C refrigerant for direct drop‑in replacement

Application Scenarios

HVAC‑R technicians, system integrators, maintenance contractors and equipment rebuilders select this Emerson BAE‑NW100 TXV for R407C systems facing variable thermal loads.

1. Residential / light‑commercial air‑to‑water heat pump retrofits: Replace failed expansion valves in existing R407C heat‑pump units requiring bi‑flow control across heating and cooling modes.
2. Packaged rooftop air‑conditioning units: Service and repair R407C rooftop AC systems exposed to wide outdoor ambient temperature fluctuations.
3. Medium‑temperature commercial refrigeration display cases: Maintain stable evaporator superheat for display coolers running R407C under shifting product heat‑load conditions.
4. HVAC equipment rebuild & component‑swap workshops: Drop‑in OEM‑equivalent replacement part for refurbishing legacy R407C cooling assemblies.
5. Light industrial process cooling units: Stabilise refrigerant metering for process chillers using R407C that experience variable process heat loads.
