Sanhua International SHF-20D-47-02 Valve
The Sanhua SHF-20D-47-02 is a heavy-duty 4-way reversing valve engineered for precision refrigerant flow control in heat pump systems. Designed as a reliable solution for switching between cooling and heating modes, this valve features a 1/2 inch ODF solder discharge connection and 7/8 inch ODF solder suction/ESC connections, ensuring a leak-resistant fit in unitary air conditioners and central HVAC units. With a robust 5.7-ton capacity (22.1 kW nominal) and a 650 PSIG maximum operating pressure, it is fully compatible with modern HFC and HCFC refrigerants, including R-410A, R-22, R-407C, and R-134a.
This pilot-operated valve utilizes a durable brass body and high-grade internal slide material capable of withstanding fluid temperatures up to 275°F. The SHF-series is widely recognized for its low pressure drop and high reliability under extreme cycling conditions. Field technicians should note that this model is the reversing valve body only; a compatible solenoid coil must be sourced separately to complete the assembly. Proper orientation (coil upwards or horizontal) is required for optimal pilot performance and long-term HVAC system diagnostics efficiency.
Key Benefits:- Broad Refrigerant Compatibility: Engineered for use with R-410A, R-407C, R-22, and R-134a systems.
- High Pressure Threshold: Rated for up to 650 PSIG to handle high-pressure heat pump applications safely.
- Precision Machined Connections: 1/2" and 7/8" ODF solder ports provide secure, professional-grade joints.
- Optimized Flow Design: Minimizes internal pressure drop to maintain system Seer/EER performance.
- Durable Construction: Built to withstand commercial-grade thermal cycling and ambient temperatures from -22°F to +122°F.
Is the solenoid coil included with this valve?
No, the Sanhua SHF-20D-47-02 is the valve body only. You must select a matching AC or DC coil based on your system's voltage requirements.
Can this valve be installed in any orientation?
The valve must be installed with the coil stem pointing upwards or with the body axis in a horizontal alignment to ensure the pilot mechanism functions correctly.
What is the maximum tonnage this valve can handle?
This specific model is rated for approximately 5.7 tons (Condition 2), making it suitable for larger residential and light commercial heat pumps.
