Ranco V10-418140-170 Reversing Valve

The Ranco V10-418140-170 Reversing Valve is a heavy-duty 4-way pilot-operated slider valve engineered for high-capacity heat pump applications, including unitary and split systems. With a 10-ton nominal capacity, this valve provides high-performance refrigerant flow control, supporting 3.0 to 11.2 tons for R22 systems and 3.8 to 13.5 tons for R410A systems. The 1 1/8" suction and 7/8" discharge connections feature copper tube extensions to facilitate clean, professional brazing in the field. Built with a hermetically sealed brass body and a Teflon-lubricated metal slide, this unit ensures minimal pressure drop and high resistance to contaminants, maintaining system efficiency during the critical transition between heating and cooling cycles. Designed to operate under full system pressure with a maximum operating pressure of 690 psig, it requires an LDK series solenoid coil (sold separately) for a complete installation. This HVAC reversing valve is a reliable solution for contractors looking to restore defrost functionality or heat pump performance in commercial and residential settings.

• High-Capacity Compatibility: Optimized for large 10-ton systems using both R22 and R410A refrigerants.
• Durable Construction: Features a hermetically sealed brass housing and stainless steel components for long-term leak prevention.
• Efficient Shifting: The PTFE metal slide reduces internal friction, ensuring smooth reversals even at low pressure differentials.
• Installation Ready: Copper inlet and outlet tubes allow for standard 1 1/8" x 7/8" connections, saving time during heat pump repair.
• Wide Operating Range: Performance-tested for temperatures ranging from -40°F to 250°F to handle extreme environmental conditions.

What solenoid coil is compatible with this valve?
The V10-418140-170 is designed to work with Ranco LDK series solenoid coils. Ensure the coil voltage matches your system's control circuit (typically 24V, 120V, or 240V).

Can I use this valve for a 5-ton system?
While the nominal capacity is 10 tons, the effective range for R410A begins at approximately 3.8 tons. Always verify that the pressure drop across the valve meets the manufacturer’s specifications for your specific tonnage to prevent oil return issues.

How do I prevent damage to the internal seals during brazing?
When installing reversing valves, always wrap the valve body in a saturated wet rag. Keep the torch flame directed away from the body and ensure the temperature does not exceed 250°F to avoid warping the internal slide or seals.
