Sanhua SHF-50015 4-Way Reversing Valve | ~39 kW R410A | 3/4" + 7/8" ODF | Coil Sold Separately

The Sanhua SHF-50015 (engineering code SHF-35B-67-02) is a pilot-operated 4-way reversing valve that switches between cooling ↔ heating by changing the refrigerant flow direction in heat pumps and reversible systems. 35-class body — selected up to 39.4 kW with R410A (ΔP 0.1 bar) and up to 55.7 kW at higher pressure drop. It is the standard valve for commercial split/packaged air conditioners, rooftop units and medium-capacity heat pumps.

4-Way Reversing Valve for Commercial Air Conditioners and Heat Pumps

The 4-way reversing valve changes the direction of the compressor discharge gas, swapping the evaporator ↔ condenser roles between the indoor and outdoor units; a single circuit provides both cooling and heating. The pilot coil is NOT INCLUDED — order separately according to voltage (for 220-240 V in Turkey, a Sanhua SHF coil is suitable).

Technical Specifications (Official Sanhua Datasheet)

• Model: Sanhua SHF-50015 | Engineering Code: SHF-35B-67-02
• Capacity (tc 38°C / to 5°C, ΔP 0.1 bar): R410A 39.4 kW · R407C 32.6 kW · R404A/R507 28 kW · R134a 25.6 kW
• Kv Value: 14.7 m³/h | Port Diameter: 20.9 mm
• Connections (ODF solder): D (discharge) 3/4" · E/S/C 7/8"
• Max. Working Pressure (PS): 45 bar — suitable for current HFC refrigerants including R410A
• Size / Weight: L 213 · A 82 · B 87 · C 100 · F 33 · G 40 mm · 1.3 kg — official dimension drawing (D-type body) in the 2nd image
• Compatible Refrigerants: R410A, R407C, R404A, R507, R134a, R22

• 🔧 Cool the body with a wet cloth during brazing and keep the flame away from the slide area — the internal PTFE slide is damaged by heat.
• Install the valve horizontally (coil on top); the installation direction must follow the flow diagram on the body.
• Verify capacity against ΔP when selecting: the same valve gives 39.4 kW at 0.1 bar drop and 55.7 kW at 0.2 bar drop (R410A).
