Daikin Applied 910000000 Reversing Valve 10 Ton Heat Pump

Product Description

The DAIKIN APPLIED 910000000 is a 4-way pilot-operated reversing valve designed for 10-ton commercial heat pump systems. It redirects refrigerant flow between heating and cooling modes using an internal slide-block mechanism, making it a core component in heat pump refrigerant circuit service. The valve features copper sweat connections sized for high-capacity refrigerant lines and is rated for use with modern high-pressure refrigerants. Licensed HVAC technicians performing a reversing valve replacement in commercial rooftop units or similar heat pump equipment will find the connection geometry suited to standard brazing procedures.

This valve is intended for commercial HVAC heat pump applications in the 10-ton capacity range. Typical installations include rooftop package units and split heat pump systems where a 4-way valve controls the direction of refrigerant flow during mode switching. The pilot-operated design is suited for high-capacity systems where direct-acting valves are not practical. Solenoid coils compatible with 24-volt or 120-volt control circuits are required but sold separately.

Key Features

• 4-way pilot-operated design for reliable refrigerant flow reversal in heat pump systems
• Rated for 10-ton HVAC capacity
• Copper sweat connections for standard brazing installation
• Compatible with 24-volt or 120-volt solenoid coils (sold separately)
• Slide-block mechanism directs flow between heating and cooling modes
• Rated for use with modern high-pressure refrigerants

Compatibility

Designed as an OEM-style replacement reversing valve for 10-ton commercial heat pump systems requiring a 4-way pilot-operated valve with copper sweat connections.

Installation Notes

Installation should be performed by a licensed HVAC technician holding an EPA Section 608 refrigerant certification. The refrigerant circuit must be recovered and the system depressurized before removing the existing valve. During brazing, heat dissipation techniques such as wet rags or heat sink compound must be applied to protect internal seals and the solenoid coil from thermal damage. Reconnect and leak-test all sweat joints before recharging the system.
