Ranco V2-4100F0-370 Reversing Valve

The Ranco V2-4100F0-370 is a heavy-duty 4-way reversing valve engineered for precision refrigerant flow control in residential and light commercial heat pump applications. Rated for a 2-ton nominal capacity, this slide-type valve is fully compatible with both R22 and R410A systems, making it a versatile drop-in for reversing valve replacement projects involving split systems, unitary units, or window-type heat pumps. Constructed with a hermetically sealed brass body and robust copper connections, it features a 5/8" suction line and a 3/8" discharge line configuration designed for minimal pressure drop and maximum high-side efficiency.

This pilot-operated mechanism utilizes the system's own high-and-low-side pressure differential to shift the internal Teflon-lubricated slide, ensuring positive reversals even at lower pressure spreads. For technicians performing HVAC troubleshooting, the V2 series is recognized for its contaminant resistance and durability under high operating temperatures. Please note that this valve requires a compatible Ranco LDK series solenoid coil (sold separately) for operation, facilitating smooth transitions between heating, cooling, and defrost modes.

• Multi-Refrigerant Support: Fully rated for R410A, R22, and other common HFC/HCFC refrigerants.
• High-Efficiency Performance: Metal slide with internal Teflon seals minimizes pressure drop to maintain SEER ratings.
• Durable Construction: The brass housing and copper sweat connections provide excellent leak resistance and ease of brazing.
• Versatile Application: Ideal for standard 2-ton heat pump systems across various residential and light commercial brands.

• What size are the ports on the V2-4100F0-370? This model features a 5/8" IDS suction connection and a 3/8" OD high-pressure discharge connection.
• Which solenoid coil should I use with this valve? This valve is designed to work with Ranco LDK Series Solenoid Coils; older L27 series coils are not compatible.
• How do I diagnose a stuck reversing valve? Measure the temperature differential across the valve; a difference greater than 3°F across the suction ports often indicates internal bypass or a mechanical failure.
